Proton emission cross sections of silicon isotopes

Measurements of the electrodisintegration cross sections, ({ital e},{ital p}) and ({ital e},2{ital p}), and their corresponding electrodisintegration-plus-photodisintegration yields for {sup 29}Si and {sup 30}Si are presented. The experiment covers the range from 20 to 60 MeV electron incident energies. The experimental results were analyzed using {ital E}1 and {ital E}2 distorted-wave Born approximation virtual photon spectra for a finite nucleus in order to obtain the corresponding photodisintegration cross sections for both channels and isotopes. For {sup 29}Si the integrated ({gamma},{ital p}) cross sections is 47% bigger than ({gamma},{ital n}) while for {sup 30}Si they are of the same order of magnitude. For both isotopes the ({gamma},{ital p}) decay channel is dominantly {ital E}1. The ({gamma},2{ital p}) channel is much smaller than the ({gamma},2{ital n}) channel but the {ital E}2 contribution to this decay mode is of the same magnitude of the {ital E}1.
