Proton Occupancies in the Even Se Ground States Via the (D, sup 3 He) Reaction.

摘要

The spectroscopic factors for the levels of sup 73 As, sup 75 As, sup 77 As, sup 79 As, sup 81 As have been measured in the Se(d, sup 3 He)As reactions at 25.2 MeV. The proton occupation numbers deduced for the even Se isotopes show that the striking change in proton configuration, observed for the Ge isotope between N = 42, does persist for the Se isotopes. This change is not reproduced, either by a model calculation using spectral distribution methods or by proton wave functions recently suggested for the Se isotopes to explain the results of the Se(d, sup 6 Li)Ge reactions.
