Vertex constants for proton separation of sd-shell nuclei from the analysis of peripheral transferring reaction

The differential cross sections of (3He, d) reaction on 16O nuclei at E3He = 42 MeV, and on 19F and 26Mg nuclei at 22.3 MeV have been carried measured in the forward hemisphere. The analysis of those data altogether with the published ones have been carries out by the method combining DWBA and Dispersion Theory. It is shown that the reactions in that region are pure peripheral. The phenomenological nuclear vertex constants and spectroscopic factors for proton separation from the ground and few lowest states of residual nuclei have been obtained in the cases of pole reaction mechanisms. The astrophysical aspects of such data are discussed
