Abstract

Abstract The angular distributions of 26Mg(p, d)25Mg deuteron groups to the levels in 25Mg up to 3.903 MeV, which were resolved with 30 keV resolution, were compared with DWBA pick-up theory. Several levels, particularly those which are weakly populated do not fit well. A spectroscopic factor analysis was made where 25Mg was assumed to consist of a deformed core with the odd neutron in a mixture of all possible N = 2 Nilsson states. The band-head spectroscopic factors then gave the filling of Nilsson states in 26Mg, as V9 = 0.57, V11 = 0.30 and V5 = 0.78. Good agreement with the spectroscopic factors for the other N = 2 particle states in 25Mg was found. However the 7 2 + and 9 2 + levels appear much more strongly than would be predicted by direct neutron pick-up theory.
