ELECTRON SCATTERING AND SPECTROSCOPY OF PSEUDO-NUCLEI

The method of Cohen, Lawson and Soper of comparing a shell-model study and an exact calculation for a two-level model (d- and f-states) is extended to the s-d shell and to the non-degenerate case. In contrast to the case of d-f states, concealed configuration interactions cannot easily occur in the s-d shell. It is shown that inelastic electron scattering provides, in principle, a sensitive test for the purity of the configurations occurring in a shell-model analysis of experimental results. © 1968.
