Abstract

The nucleus 152Sm is characterized by a variety of low-energy collective modes, conventionally described as rotations, β vibrations and γ vibrations. Recently, it has been suggested that 152Sm is at a critical point between spherical and deformed collective phases. Consequently, 152Sm is being studied by a variety of techniques, including radioactive decay, multi-step Coulomb excitation, in-beam (α, 2nγ) γ-ray spectroscopy and (n, n′γ) spectroscopy. The present work focuses on the latter two reactions; these have been used to investigate the low-lying bands associated with the octupole degree of freedom, including one built on the first excited 0+ band. In addition, the Kπ ≤ 4+ hexadecapole vibrational band has been identified.
