Abstract

The level scheme of the N=78 nucleus ${}^{140}{Sm}$ has been investigated via in-beam gamma-ray spectroscopy using the ${}^{114}{Cd}$ $(^{30}$ Si, 4n) reaction. States up to I=22 and $E_{x}$ =8101 keV have been established. The level structure above the known isomeric $10^{+}$ states is discussed in terms of the coupling between the valence particles or holes and the N=78 and N=80 cores.
