Identification of γ transitions in 147Ba, 149Ce, and 151,153Nd
Abstract
The γ transitions in 147Ba, 149Ce, and 151,153Nd have been identified from γ-γ-γ, γ-γ, x-γ, and x-γ-γ coincidence studies of spontaneous fission of 252Cf. The yrast positive parity band in 149Ce is assigned to an i13/2, neutron favored signature. The yrast negative parity band in 149Ce is assigned a h9/2 proton favored signature. The positive parity band in 151Nd corresponds to the positive parity band in 149Ce. The negative parity band in 153Nd corresponds to the negative parity bands of 149Ce and 161Er. The band observed in 147Ba is built on the h9/2 orbital. The plots for J1 in these isotopes are remarkably similar, supporting our assignments.
