Neutron single-particle states above the N=164 subshell in 98 251 Cf and 96 249 Cm studied by neutron transfer reactions

摘要: Single-particle state assignments in $^{251}\mathrm{Cf}$ and $^{249}\mathrm{Cm}$ at $~1$ MeV excitation have been deduced from cross sections previously measured for the $^{250}\mathrm{Cf}(d,p)^{251}\mathrm{Cf}$ $^{248}\mathrm{Cm}(^{4}\mathrm{He},^{3}\mathrm{He})^{249}\mathrm{Cm}$ reactions. The are supported by observed cross-section signatures intraband level spacings. energies of these single-particle states, after pairing effects removed, good agreement with values calculated using a Woods-Saxon potential. Neutron diagrams, showing spacings as function ${\ensuremath{\nu}}_{2},{\ensuremath{\nu}}_{4},$ ${\ensuremath{\nu}}_{6}$, extended to include neutron orbitals above $N=164$.
