# Low Energy States of $^{81}_{31}$Ga$_{50}$ :\\ Elements on the Doubly-Magic Nature of $^{78}$Ni

Abstract : Excited levels were attributed to $^{81}_{31}$Ga$_{50}$ for the first time which were fed in the $\beta$-decay of its mother nucleus $^{81}$Zn produced in the fission of $^{nat}$U using the ISOL technique. We show that the structure of this nucleus is consistent with that of the less exotic proton-deficient $N=50$ isotones within the assumption of strong proton $Z=28$ and neutron $N=50$ effective shell effects.
