ONE-NUCLEON REMOVAL REACTIONS AS A TEST OF OVERLAP FUNCTIONS FROM THEONE-BODY DENSITY-MATRIX CALCULATIONS

Overlap functions and spectroscopic factors extracted from a model one -body density matrix (OBDM) accounting for short-range nucleon-nucleon correlations are used to calculate differential cross sections of (p, d) reactions and the momentum distributions of transitions to single-p article states in O-16 and Ca-40. A comparison between the experimenta l (p, d) and (e, e'p) data, their DWBA and CDWIA analyses and the OBDM calculations is made. Our theoretical predictions for the spectroscop ic factors are compared with the empirically extracted ones. It is sho wn that the overlap functions obtained within the Jastrow correlation method are applicable to the description of the quantities considered.
