Three-quasiparticle isomers in odd-even 159, 161Pm: Calling for modified spin-orbit interaction for the neutron-rich region
RADIOACTIVITY 159,161Pm(IT)[from 9Be(238U, F), E=345 MeV/nucleon, followed by separation of fission fragments using the BigRIPS in-flight separator and implantation of fragments in WAS3ABi setup at RIBF-RIKEN facility]; measured Eγ, Iγ, γγ-coin, half-lives of the isomers by γ(t) using the EURICA array of 12 EUROBALL clusters. 159,161Pm; deduced high-spin levels, J, π, bands, 2-quasiparticle Nilsson configurations for the isomeric states, and 3-quasiparticle configurations from theory, existence of the deformed N=98 subshell gap in odd-mass nuclei. Comparison with projected shell model (PSM) calculations. Discussed modification of strength of spin-orbit interactions in standard Nilsson parameters for neutron-rich rare-earth nuclei around A=165.
