More than 50 years ago, in 1934, Chadwick and Goldhaber (ChG 34) published a paper entitled "A 'Nuclear Photo-effect': Disintegration of the Diplon by -y-Rays."l in the introduction: They noted "By analogy with the excitation and ionisation of atoms by light, one might expect that any complex nucleus should be excited or 'ionised', that is, disintegrated, by -y-rays of suitable energy", and furthermore: "Heavy hydrogen was chosen as the element first to be examined, because the diplon has a small mass defect and also because it is the simplest of all nuclear systems and its properties are as important in nuclear theory as the hydrogen is in atomic theory". Almost at the same time, in 1935, the first theoretical paper on the photodisinte gration of the deuteron entitled "Quantum theory of the diplon" by Bethe and Peierls (BeP 35) appeared. It is not without significance that these two papers mark the be ginning of photonuclear physics in general and emphasize in particular the special role the two-body system has played in nuclear physics since then and still plays. A steady flow of experimental and theoretical papers on deuteron photo disintegration and its inverse reaction, n-p capture, shows the continuing interest in this fundamental process (see fig. 1.1).

The decay product of the medical isotope molybdenum-99 (Mo-99), technetium-99m (Tc-99m), and associated medical isotopes iodine-131 (I-131) and xenon-133 (Xe-133) are used worldwide for medical diagnostic imaging or therapy. The United States consumes about half of the world's supply of Mo-99, but there has been no domestic (i.e., U.S.-based) production of this isotope since the late 1980s. The United States imports Mo-99 for domestic use from Australia, Canada, Europe, and South Africa. Mo-99 and Tc-99m cannot be stockpiled for use because of their short half-lives. Consequently, they must be routinely produced and delivered to medical imaging centers. Almost all Mo-99 for medical use is produced by irradiating highly enriched uranium (HEU) targets in research reactors, several of which are over 50 years old and are approaching the end of their operating lives. Unanticipated and extended shutdowns of some of these old reactors have resulted in severe Mo-99 supply shortages in the United States and other countries. Some of these shortages have disrupted the delivery of medical care. Molybdenum-99 for Medical Imaging examines the production and utilization of Mo-99 and associated medical isotopes, and provides recommendations for medical use.

Dorian's Dictionary of Science and Technology: English-German, Second Revised Edition focuses on the compilation of terms employed in science and technology. The book first takes a look at abduction, aberration, abhesion, abating, ablation, abscission, coupling, covering, back iron, cross-breeding, clip, cleats, channel, circuit diagram, connection, conveyors, and supercharger. The manuscript then takes a look at dabbing, dacite, dactyl, daffodil, damp, earmark, earphone, ripening, current prospecting, facilities, gaff, gablet, galaxy, gale, gait, gall, and galipot. The publication ponders on haddock, Hadley quadrant, H-bomb, habitation, habituation, hemoglobin, hailstorm, hail, halation, ichnography, iceboat, oblate, oblique, electrode structure, obesity, oatmeal, dyeing, and pachyderm. The text then explores wainscoting, waist, wale, waiver, ultrafilter, ultrahigh frequency, ulocarcinoma, elongation, vaccinal fever, vaccination, vaccine, vacancy, and vacuometer. The text is a dependable source of data for researchers interested in the terms used in science and technology.

This bibliography is a revision of the Bibliography of Photonuclear Reactions, October 1960. References are included for theoretical and experimental results published in standard periodicals and proceedings of conferences. Various governmental and institutional reports have been omitted due to their limited distributions. Studies of photon absorption and excitation of nuclei have been included when they have been equivalent to the initial part of photonuclear disintegrations. Results concerning bremsstrahlung spectra and intensity and other photon sources have been included. Photomeson production and photo-induced radioactivity in order to study the resulting nuclei have been excluded. The references are listed for reactions with light nuclei, through neon, under each element; for reactions with heavier elements, the references are listed under the type of reaction. Each reference has been coded under the lightest element or under the reaction which was the principal part of the investigation. Whenever an investigation concerns more than one light element or type of reaction, its code number is given in the ''see also'' listings of its other elements or types of reactions other than the principal one.
