Abstract

A new experimental investigation of the level scheme of the $N = Z + 1$ nucleus ${}^{81}{Zr}$ is reported. An additional band assigned to the $[431] 1 ∕ 2^{+}$ orbital has been observed and the known $[422] 5 ∕ 2^{+}$ and $[301] 3 ∕ 2^{-}$ bands have been extended to higher spins. The behavior of these bands is compared to that of the bands in the isotonic nucleus ${}^{79}{Sr}$ , for which some new experimental data are presented. Comparison is also made to the even-even $N = Z$ and $N = Z + 2$ neighbors. The band structures are discussed in the framework of the projected shell model.
