Generator coordinate method calculations of one-nucleon removal reactions on Ca-40 - art. no. 014605

An approach to the generator coordinate method (GCM) using Skyrme-type effe ctive forces and Woods-Saxon construction potential is applied to calculate the single-particle proton and neutron overlap functions in Ca-40. The rel ationship between the bound-state overlap functions and the one-body densit y matrix has been used. These overlap functions are applied to calculate th e cross sections of one-nucleon removal reactions such as (e,e'p), (gamma , p), and (p,d) on Ca-40 on the same theoretical footing. A consistent descri ption of data for the different reactions is achieved. The shapes of the ex perimental cross sections for transitions to the 3/2(+) ground state and th e first 1/2(+) excited state of the residual nuclei are well reproduced by the overlap functions obtained within the GCM. An additional spectroscopic factor accounting for correlations not included in the overlap function mus t be applied to the calculated results to reproduce the size of the experim ental cross sections.
