GLOBAL SYSTEMATICS OF NUCLEAR OBSERVABLES IN ODD-A NUCLEI

摘要

Different correlations between observables related to the unique parity orbital struc-tures in the odd-A nuclei are studied. It is shown that the correlations between excitation energies within the unique parity orbital quasibands allow a tripartite classification of the evolution of the nuclear structure, similar to that observed in the adjacent even-even nuclei: all nuclei can be assigned to three different regimes, the precollective, anharmonic vibrator and strong coupling, respectively, intercon-nected by fast, critical phase-like transitions. It is also shown that both an index which characterizes the signature splitting, and the B(E2) values within the quasi-bands can be organized in terms of a valence correlation scheme.
