Jastrow-Type Calculations of One-Nucleon Removal Reactions in Open s-d Shell Nuclei

Single-particle overlap functions and spectroscopic factors are calculated on the basis of Jastrow-type onebody density matrices of open-shell nuclei constructed by using a factor cluster expansion. The calculations use
the relationship between the overlap functions corresponding to bound states of the (A-1)-particle system and the one-body density matrix for the ground state of the A-particle system. In this work, we extend our previous
analyses of reactions on closed-shell nuclei by using the resulting overlap functions for the description of the
cross sections of (p,d) reactions on the open s-d shell nuclei 24Mg, 28Si, and 32S and of 32S(e,e'p) reaction.
The relative role of both shell structure and short-range correlations incorporated in the correlation approach onthe spectroscopic factors and the reaction cross sections is pointed out.
