Abstract

High-spin excited states in the neutron-rich nucleus ${}^{140}{Cs}$ were re-investigated from the spontaneous fission of ${}^{252}{Cf}$ with the Gammasphere detector array. Seven new transitions at low and moderate spin and 13 at high spin were observed in ${}^{140}{Cs}$ and the level scheme of ${}^{140}{Cs}$ was extended to 3794 keV with a new sideband. Spins and parities were assigned to levels based on angular correlation measurements and the systematics in the $N = 85$ isotones.
