Study of Some (Sd)/sup 4/ Shell Model States in /sup 20/F Via the /sup 18/O(/sup 3/He,p) Reaction

摘要

A microscopic two-particle DWBA analysis is carried out on the /sup 18/O(/sup 3/He,p)/sup 20/F reaction leading to the (sd)/sup 4/ positive parity levels. The spectroscopic amplitudes were derived from the three single particle energies and sixty-three two-body matrix elements given by the shell model calculations or Halbert et al. based on an inert /sup 16/O core with the additional nucleons distributed in an unrestricted 1d/sub 5/2/-2s/sub 1/2/-1d/sub 3/2/ model space. Angular distributions leading to several 1/sup +/, 2/sup +/, 3/sup +/, 4/sup +/ and 5/sup +/(sd)/sup 4/ levels in /sup 20/F are fairly well reproduced. (author). 21 refs, 4 figs, 3 tabs.
