Terminating states in the positive-parity structures of As 67

Journal Article · · Physical Review C

The energy levels and gamma-ray decay scheme of the positive-parity states in the T-z = 1/2 nucleus As-67 have been studied by using the Ca-40(Ar-36, 2 alpha p)As-67 reaction at a beam energy of 145 MeV. Two new band structures have been identified which can be connected to the previously known levels. The results for these bands are compared with configuration-dependent cranked Nilsson-Strutinsky calculations. The good level of agreement between theory and experiment suggests that these structures can be interpreted in terms of configurations that involve three g(9/2) particles and that both possess noncollective terminating states.
