Abstract

High resolution inelastic electron scattering measurements on ${}^{140}{Ce}$ have led to the identification of a $J^{π}$ ${= 12}^{-}$ state at 6.31 MeV. This transition has only 8% of the calculated single-particle strength. The absence of strong transverse excitations is interpreted as evidence for fragmentation of the single-particle strength.
