Description: Preliminary results and data are given for eight expenimental and theoretical nuclear physics projects under investigation. Those projects not reported are listed separately with a reference to the last issue in which each appeared. Separate abstracts were prepared for the eight activities. (For preceding period see ANL-6214.) (W.D.M.)

Reactor Physics Primer

Description: An introduction for the beginner to the fundamentals of nuclear physics is presented, dealing genernlly with the reactor physics aspects of the processes used at Hanford in the production of plutonium. The information is presented primarily for reactor operators and is intended as an aid toward better understanding of crucial pile conditions, as a training guide for new personnel, and as a source of subject matter for group discussion.

Description: The successes and difficulties of the Bloch model of a metal are briefly reviewed, and the Landau quasi-particle theory amd the pseudopotential theory are briefly discussed. These two notions are made the basis for a revised version of the Bloch model that avoids the conceptual difficulties of the original model, while retaining and explaining its appealing features. Well known empirical generalizations concerning the relative importance of conduction-electron density, composition, and structure for the electronic properties are presented, and their implications are reexamined. A theory of the form required by the empirical generalizations is developed. Recent approximate calculations are discussed, and a variety of conclusions are drawn from these relating to the possibility of explanation of the empirical generalizations by the theory. 42 references.

Nuclear Structure at the Limits

Description: One of the frontiers of today�s nuclear science is the �journey to the limits� of atomic charge and nuclear mass, of neutron-to-proton ratio, and of angular momentum. The tour to the limits is not only a quest for new, exciting phenomena, but the new data are expected, as well, to bring qualitatively new information about the fundamental properties of the nucleonic many-body system, the nature of the nuclear interaction, and nucleonic correlations at various energy-distance scales. In this series of lectures, current developments in nuclear structure at the limits are discussed from a theoretical perspective, mainly concentrating on medium-mass and heavy nuclei.

Time independent mean-field theory

Description: The physical and theoretical motivations for the time-dependent mean-field theory are presented, and the successes and limitations of the time-dependent Hartree-Fock initial-vaue problem are reviewed. New theoretical developments are described in the treatment of two-body correlations and the formulation of a quantum mean-field theory of large-amplitude collective motion and tunneling decay. Finally, the mean-field theory is used to obtain new insights into the phenomenon of pion condensation in finite nuclei. 18 figures.

Theory of hybrid nuclear reactions

Description: A theory of hybrid nuclear reactions, which are partially direct and partially compound, is presented. We review first the formulation of the theory, based on the optical theorem, and then its applications to a few example reactions. Discussions will be given on the physical picture (deep peripheral nature) of such hybrid processes emerging from the numerical studies. 25 references, 10 figures.

Description: The energy levels predicted by Davydov and Chaban's model were computed to compare theoretical predictions with experimental results. The computations were carried out for mu between 1.0, 0.90, 0.40, 0.35, and 0.1 and for gamma between 8, 9, 10, 12, 15, 20, 25, and 30 deg . (W.L.H.)

Fractional Parentage Coefficients in Intermediate Coupling

Description: Fractional parentage coefficients are obtained which connect certain low- lying states in the 1p shell without the necessity of referring to either an LS or jj representation. The possibility of doing this algebraically is based on the generator method of producing the wave functions of these states. (auth)
