Abstract

Results are reported for angular distributions of the reaction Zr90(He3, t)Nb90 at 21 MeV. It is found that for targets in the f72 shell this reaction favors specific final states in which a neutron is replaced by a proton in the same shell-model orbit, coupled to any allowed angular momentum. The angular distributions differ in a systematic way depending on the spin of the final state. The nine states of the T< (g92)2 multiplet are tentatively identified. A multipole decomposition leads to coefficients very similar to those of the (f72)2 multiplet, showing an enhanced quadrupole coefficient.
