Shell-model calculation of the spectral function for l=0 proton states in12C

Abstract

The spectral function for the removal of /=0 protons in 12C is calculated within the framework of the shell model. The techniques used in the calculation exploit, in a novel fashion, certain features of the Lanczos method used in obtaining energies and wavefunctions. Gross and fine details of the resulting strength distributions are compared against the results from 12 C(e, e'p) ~ aB experiments.
