DOWNLOAD EBOOKThis book introduces a quantum-mechanical description of the nuclear fission process from an initial compound state to scission. Issues like the relevant degrees of freedom throughout the process, the way of coupling collective and intrinsic degrees during the fission process, and how a nucleus divides into two separate daughters in a quantum-mechanical description where its wave function can be non-local, are currently being investigated through a variety of theoretical, computational, and experimental techniques. The term “microscopic” in this context refers to an approach that starts from protons, neutrons, and an effective (i.e., in-medium) interaction between them. The form of this interaction is inspired by more fundamental theories of nuclear matter, but still contains parameters that have to be adjusted to data. Thus, this microscopic approach is far from complete, but sufficient progress has been made to warrant taking stock of what has been accomplished so far. The aim is to provide, in a pedagogical and comprehensive manner, one specific approach to the fission problem, originally developed at the CEA Bruyères-le-Châtel Laboratory in France. Intended as a reference for advanced graduate students and researchers in fission theory as well as for practitioners in the field, it includes illustrative examples throughout the text to make it easier for the reader to understand, implement, and verify the formalism presented.

DOWNLOAD EBOOKThis book brings together various aspects of the nuclear fission phenomenon discovered by Hahn, Strassmann and Meitner almost 70 years ago. Beginning with an historical introduction the authors present various models to describe the fission process of hot nuclei as well as the spontaneous fission of cold nuclei and their isomers. The role of transport coefficients, like inertia and friction in fission dynamics is discussed. The effect of the nuclear shell structure on the fission probability and the mass and kinetic energy distributions of the fission fragments is presented. The fusion-fission process leading to the synthesis of new isotopes including super-heavy elements is described. The book will thus be useful for theoretical and experimental physicists, as well as for graduate and PhD students.

DOWNLOAD EBOOKThis volume collects the contributions to the international conference "Nuclear Structure and Dynamics", held in Dubrovnik, Croatia, from May 4 to 8, 2009. The conference was hosted by the Physics Department of the University of Zagreb and the Ruder Boškovic Institute. Following the long tradition of nuclear physics meetings on the Adriatic coast, organized by our two institutions, the Conference presented a review of recent experimental and theoretical advances in the physics of nuclear structure and reactions, and provided a broad discussion forum on current and future research projects. The main focus was on the following topics: Nuclear structure and reactions far from stability - Exotic modes of excitation and decays - Collective phenomena and symmetries - Ab initio, cluster model, and shell-model approaches - Nuclear energy density functionals - Heavy-ion reactions at near-barrier energies - Dynamics of light-ion reactions - Nuclear reactions of astrophysical interest - Weak-interaction processes. More than 170 nuclear physicists from over 30 countries participated in "Nuclear Structure and Dynamics". The considerable interest in this meeting was reflected not only in the number of participants but also in the large number of received abstracts. Following the suggestions of the International Advisory Committee, only about half of the submitted abstracts could be selected for oral presentation. In addition to 24 invited talks, more than 80 oral contributions were presented. An evening poster session was organized as part of the conference. An effort was made to provide the opportunity for young researchers to present their work, and selected posters were accepted for very short oral presentation.

DOWNLOAD EBOOKLarge-amplitude collective motion in fission and heavy-ion reactions is studied by solving classical equations of motion for the time evolution of the nuclear shape. In the nuclear potential energy of deformation, the generalized surface energy was calculated by means of a double volume integral of a Yukawa-plus-exponential function, which was obtained by requiring that two semi-infinite slabs of constant-density nuclear matter have minimum energy at zero separation. The collective kinetic energy is calculated for nuclear flow that is a superposition of incompressible, nearly irrotational collective-shape motion and rigid-body rotation. Nuclear dissipation is included by means of the Rayleigh dissipation function, which depends upon the physical mechanism that converts collective energy into internal energy. For both ordinary two-body viscosity and a combined wall and window one-body dissipation, fission-fragment kinetic energies are calculated for the fission of nuclei throughout the periodic table and compare with experimental results. Finally, the one-body dynamics of nucleons inside a cylinder colliding with a moving piston is explicitly studied by solving exactly the collisionless Boltzmann equation for the distribution function. By examining the relative phases of the pressure at the piston and the piston's velocity, a dissipative force and an elastic restoring force can be separately identified. 9 references.
