Smooth band termination in 115I

Petrache, C.M. and Ragnarsson, Ingemar LU (2025) In Physical Review C 112(054315).
Abstract
The cranked Nilsson-Strutinsky formalism is employed to investigate the band structure of 115I from low to high spin. A set of eight rotational bands with well established spins and parities are analyzed. Five bands start at low spin and are assigned to the single-particle proton orbitals (𝑑5/2, 𝑔7/2), 𝑔9/2, and ℎ11/2, which are close to the Z = 53 Fermi surface for a deformation of ɛ2=0.2. The analysis of the observed level energies relative to a rotating liquid drop and spins versus 𝛾-ray energies allow one to track the evolution of the configurations with increasing spin. It is of special interest that one band in the valence space is observed to terminate smoothly at 𝐼max=67/2+.
