Abstract

High-spin states in ${}^{157}{Yb}$ have been populated in the ${}^{144}{Sm}$ ( ${}^{16}O$ ,3 $n$ ) ${}^{157}{Yb}$ fusion-evaporation reaction at a beam energy of 85 MeV. Two rotational bands built on the $ν f_{7 / 2}$ and ν $h$ $_{9 / 2}$ intrinsic states, respectively, have been established for the first time. The newly observed ν $f$ $_{7 / 2}$ band and previously known ν $i$ $_{13 / 2}$ band in ${}^{157}{Yb}$ are discussed in terms of total Routhian surface methods and compared with the structures in the neighboring $N$ $=$ 87 isotones. The structural characters observed in ${}^{157}{Yb}$ provide evidence for shape coexistence of three distinct shapes: prolate, triaxial, and oblate. At higher spins, both the ν $f$ $_{7 / 2}$ band and ν $i$ $_{13 / 2}$ band in ${}^{157}{Yb}$ undergo a shape evolution with sizable alignments occurring.
