Abstract

Deuterons accelerated to 34.4 MeV were used to investigate the (d, 3He) reaction on 48Ti and on the N = 28 nuclei 48Ca, 50Ti, 51V, 52Cr and 54Fe. The angular distributions were compared with local zero-range DW calculations from which the transferred angular momenta and spectroscopic factors were deduced. The results are consistent with the simple shell model considering f 7 2 protons outside an inert 48Ca core. Small deviations from this description are found for 54Fe where evidence for both f 5 2 and p 3 2 admixtures are noted in the ground state. For the N = 28 nuclei it was found that the 1 d 3 2 proton shell is more tightly bound than the 2 s 1 2 proton shell.
