Seniority and $(\frac{9}{2}{)}^n$ configurations in neutron-rich Nickel isotopes

S. Sidorov, D. Zhulyaeva, T. Tretyakova

Excited states in low-energy spectra in ${}^{70-76}$Ni are considered. To this end, pairing forces in form of surface delta interaction are employed to account for formation of the g…
