摘要: High-spin states in ${}^{128}\mathrm{Ca}$ were populated with the ${}^{92}\mathrm{Mo}$ ${(}^{40}\mathrm{Ca},2p2n)$ reaction at a beam energy of 184 MeV. The previously known ground-state band has been extended to ${I}^{\ensuremath{\pi}}{=(34}^{+})$ and four sidebands observed. Configuration assignments for these are discussed based on their alignment behavior. A significant delay $\ensuremath{\nu}{h}_{11/2}$ crossing frequency is observed $A\ensuremath{\sim}130$ region, largest delays occurring consistently $N=70.$ Cranked shell model calculations performed order investigate whether variation deformation and/or pairing parameters can account this phenomenon.
