Investigations of the structure and electromagnetic interactions of few body systems. Annual progress report, 1 September 1982-31 August 1983
The George Washington University nuclear theory group proposes to conduct investigations of the structure and electromagnetic interactions of few-body systems. The structural properties of the very light nuclei are examined by developing theoretical models that begin from the basic interactions between the constituents and that are solved exactly (numerically), i.e., full three- or four-body dynamics. Such models are then used in an attempt to understand the details of the strong and electromagnetic interactions of the few-nucleon nuclei after the basic underlying reaction mechanisms are understood with simpler models. These efforts are becoming increasingly important with the advent of high duty cycle, high current electron accelerators from which valuable data will be forthcoming that should permit unraveling the structure and interactions of the very-light nuclei. Examples of specific work proposed are the following: 1) Set up the equations for the low-energy photodisintegration of /sup 3/He and /sup 3/H including final-state interactions and the E1 plus E2 operators; 2) Develop a unified picture of the p + d ..-->.. /sup 3/He + ..gamma.., p + d ..-->.. /sup 3/He + ..pi../sup 0/, p + d ..-->.. /sup 3/H + ..pi../sup +/ reactions at intermediate energies; 3) Calculate the elastic and inelastic (1/sup +/..-->..0/sup +/) form factors for /sup 6/Li with three-body (..cap alpha..NN) wave functions; 4) Calculate static properties (RMS radius, magnetic moment, and quadrupole moment) of /sup 6/Li with three-body wave functions; and 5) Develop the theory for the coincidence reactions /sup 6/Li(p,2p)n..cap alpha.., /sup 6/Li(e,e'p)n..cap alpha.., and /sup 6/Li(e,e'd)..cap alpha... It is anticipated that these efforts will expand the frontiers of our knowledge about few-body nuclei.
