摘要: Systematic features of the signature inversion phenomenon in (h 11/2)p ⊗(i 13/2)n doubly-odd rare-earth nuclei are presented. These generally observed high-j orbitals, mainly, 9/2),(h 11/2) and (i 13/2). Calculations carried out within framework two quasiparticle plus rotor model (TQPRM) to explain strong odd–even staggering these orbitals. The shifting point lower/higher spin with increase neutron/proton numbers is well explained by calculations. It found that 1 /2[541] proton orbital h 9/2 necessary lower mass region obtain inversion.
