π h 11 / 2 rotational structure in the neutron-deficient rare-earth nucleus Pm 131
Year: 2026
Type: article
Abstract: High-spin states in the neutron-deficient nucleus Pm 70 61 131 have been investigated using the 3 γ -ray spectrometer. This is the lightest promethium isotope with known excited states. The proton intruder h 11 / 2 rotational structure has been extended to both higher and lower spin, and its unfavored-signature partner identified. This rotational structure is established down to a presumed I π = 5 / 2 − bandhead of the π h 11 / 2 [ 532 ] 5 / 2 − Nilsson orbital, which is also expected to form the ground state of this deformed nucleus. Systematic comparisons are made with cranked shell-model calculations.
