Shell Structure of Ag-107,Ag-109 Nuclei and Spin-Parities Nuclei in Which the 1g(9/2) Orbit Is Being Filled

摘要

Occupation numbers and energies of proton and neutron orbits in the isotopes Ag-107 and Ag-109 were obtained on the basis of data on nucleon-stripping and nucleon-pickup reactions. A special data-analysis method reducing systematic and statistical uncertainties was applied in relevant calculations. It is shown that, in this region, the spin-parity of nuclei is determined by shells, pairing, and polarization. The schemes of proton and neutron (sub)orbits were constructed. These schemes explain the ground-state spin-parities of N, Z = 39-49 nuclei.
