Nuclear structure studies via neutron interactions

Research performed consisted of: refinement of previous analysis of high resolution total cross sections for n + 40Ar in an effort to remove some ambiguities in Jπ assignments and completion of two papers dealing with this analysis and a comparison theoretical treatment of the associated scattering functions and R-functions; extension of the analysis of neutron total cross section data on 48Ca to 3.5 MeV in neutron energy and modeling of the results with a dispersive optical model based on parameters from 40Ca scattering data; attempted improvement of spin and parity assignments for data on 122Sn and determination of external R-function parameters; development of a graphical interface, coupled with a code for calculation of R-matrix based total cross sections and parameter minimization, for an MS-DOS-based microcomputer. 11 refs., 13 figs
