SYSTEMATICS OF SIGNATURE INVERSION IN DOUBLY-ODD NUCLEI AND THE ROLE OF THE 1/2[541] PROTON ORBITAL

摘要

Some general systematic features of the signature inversion phenomenon in doubly-odd lighter rare-earth nuclei are presented. Schematic calculations are carried out within the framework of the two-quasiparticle plus rotor model (TQPRM) to explain these features, It is found that the systematics can be well explained if the h(9/2) : 1/2[541] proton orbital is included in the calculations in addition to the complete set of h(11/2) proton and i(13/2) neutron orbitals.
