Abstract:
Line broadening and orbit dependence of the Coulomb displacement energy have been observed for the 1g9/2, 2p1/2 and 2p3/2 hole-state analogs in a series of odd-A Sn isotopes. The observed widths are discussed in terms of spreading width with main contributions from mixing with the isovector monopole state as well as the escape width.
