With the availability of intense beams of greatly improved energy resolution from LAMPF, interest in intermediate energy nuclear physics is at a high level. A major interest of the Oregon State University group is the study of elastic and inelastic scattering of pions from nuclei. Since pions exhibit several features not shared by low-energy nuclear projectiles they are especially interesting objects with which to probe nuclear structure in scattering experiments. This report contains a summary of instrumentation projects, and results from the experimental programs.

This report summarizes the work on experimental research in intermediate energy nuclear physics carried out at New Mexico State University in 1991 under a great from the US Department of Energy. Most of these studies have involved investigations of various pion-nucleus interactions. The work has been carried out both with the LAMPF accelerator at the Los Alamos National Laboratory and with the cyclotron at the Paul Scherrer Institute (PSI) near Zurich, Switzerland. Part of the experimental work involves measurements of new data on double-charge-exchange scattering, using facilities at LAMPF which we helped modify, and on pion absorption, using a new detector system at PSI that covers nearly the full solid-angle region which we helped construct. Other work involved preparation for future experiments using polarized nuclear targets and a new high-resolution spectrometer system for detecting [pi]° mesons. We also presented several proposals for works to be done in future years, involving studies related to pi-mesonic atoms, fundamental pion-nucleon interactions, studies of the difference between charged and neutral pion interactions with the nucleon, studies of the isospin structure of pion-nucleus interactions, and pion scattering from polarized 3He targets. This work is aimed at improving our understanding of the pion-nucleon interaction, of the pion-nucleus interaction mechanism, and of nuclear structure.

This report summarizes the work on experimental research in intermediate energy nuclear physics carried out at New Mexico State University in 1991-94 under a grant from the U.S. Department of Energy. Most of these studies involved investigations of various pion-nucleus interactions and nucleon-nucleus charge-exchange reactions. The work was carried out with the LAMPF accelerator at the Los Alamos National Laboratory and the cyclotrons at the Paul Scherrer Institute (PSI) near Zurich, Switzerland, at Indiana University (IUCF), and at TRIUMF in Vancouver, Canada, as collaborative efforts among several laboratories and universities. We have also worked on plans and preparations for new experiments involving studies of the quark structure of nucleons and nuclei, which would be carried out at Fermilab (FNAL), near Chicago, and at the HERA facility at the DESY laboratory in Hamburg, Germany. The NMSU personnel included two faculty members, five postdoctoral research associates, nine graduate students, and one undergraduate student.

This report summarizes the work on experimental research in intermediate energy nuclear and particle physics carried out by New Mexico State University in 1988--91. Most of these studies have involved investigations of neutron-proton and pion-nucleus interactions. The neutron-proton research is part of a program of studies of interactions between polarized nucleons that we have been involved with for more than ten years. Its purpose has been to help complete the determination of the full set of ten complex nucleon-nucleon amplitudes at energies up to 800 MeV, as well as to continue investigating the possibility of the existence of dibaryon resonances. The give complex isospin-one amplitudes have been fairly well determined, partly as a result of this work. Our work in this period has involved measurements and analysis of data on elastic scattering and total cross sections for polarized neutrons on polarized protons. The pion-nucleus research continues our studies of this interaction in regions where it has not been well explored. One set of experiments includes studies of pion elastic and double-charge-exchange scattering at energies between 300 and 550 MeV, where our data is unique. Another involves elastic and single-charge-exchange scattering of pions from polarized nuclear targets, a new field of research which will give the first extensive set of information on spin-dependent pion-nucleus amplitudes. Still another involves the first set of detailed studies of the kinematic correlations among particles emitted following pion absorption in nuclei.

One of the main goals of intermediate energy nuclear physics, which serves an important role as a bridge between nuclear and particle physics, is to construct the theory of strong interaction phenomena in terms of conventional degrees of freedom (nucleons, deltas and mesons) as well as of quark degrees of freedom.The main topics to be discussed at this conference are the interaction of pions and other mesons with nuclei at intermediate energies and the role of mesonic degrees of freedom in nuclear reactions, including photon, hadron and heavy ion induced reactions. Both theoretical and experimental results will be included.Over the past two decades, the Meson Factories, including LAMPF, TRIUMF, and PSI, have provided us with systematic experimental information on hadron-hadron and hadron-nucleus dynamics. Major accelerators of JINR are also suitable for studying problems in Intermediate Energy Nuclear Physics. At the present time, first experiments have been performed with the proton beams at the Moscow Meson Factory of INR. One of the purposes of this conference is to introduce the intermediate-energy physics community to the possibility of utilizing the facilities of JINR and INR during the next decade.

The Brentwood Summer Institute on Nuclear and Particle Physics at Intermediate Energies was the second of its kind organised by the TRIUMF group of Universities, the first taking place at Banff in 1970. With the advent of initial beams at the new meson facilities at LAMPF, SIN, NEVIS, CERN S.C. and TRIUMF it was an eminently suitable time for an in-depth study of some of the science which will be possible when these accelerators achieve their design intensities in proton and meson beams. The organizing committee, comprising: Univ. of Alberta G.A. Beer Univ. of Victoria J.M. Cameron J.M. McMillan U.B.C. D.F. Measday U.B.C. R.M. Pearce Univ. of Victoria J.E.D. Pearson U.B.C. J.B. Warren U.B.C. wishes to acknowledge the financial support provided by the North Atlantic Treaty Organisation, the National Research Council of Canada, and Atomic Energy of Canada Ltd., without which the Institute could not have been held. Also we wish to acknowledge the helpful advice of the Scientific Committee of NATO and of Dr. T. Kester, Secretary of this Committee. Many persons from the University of Victoria and the University of British Columbia helped with the local arrangements and we are grateful to them and particularly to the staff of Brentwood College who made the stay of the participants such a pleasant one.

Intermediate-Energy Nuclear Physics is devoted to discussing the interaction between hadrons with nuclei, which leads to the emission of particles during an intranuclear cascade and subsequent decay of a highly excited residual nucleus. Experimental data and the methods and results of the calculation of probabilities of various processes initiated by intermediate-energy hadrons in nuclei are set forth and discussed. The potential for obtaining information on the structure and properties of nuclei by comparing experimental data with theoretical results is analyzed. New issues, such as analytic methods for the solution of kinetic equations describing the cascade, nuclear absorption of hadrons from bound states of hadronic atoms, interaction of antinucleons with nuclei, multifragmentation of highly excited residual nuclei, and polarization phenomena, are discussed in detail. The book also demonstrates hadron-nucleus interactions that bridge the gap between low-energy and heavy ions physics. It is an interesting reference for nuclear physicists and other researchers interested in the analysis of problems associated with the evolution of the early (hot) universe, neutron stars and supernovas, after-burning of radioactive waste in nuclear energy installations, and electronuclear energy breeding.
