Highest spin n<i>-</i>p states in heavy nuclei via the (<i>α</i>,<i>d</i>) reaction at 218 MeV

Abstract

Strong transitions to high spin states are observed in the study of the (\ensuremath{\alpha},d) reaction at 218 MeV on closed shell heavy nuclei. It is shown that the highest spin valence valence n-p strength in the residual nuclei $^{92}\mathrm{Nb}$, $^{122}\mathrm{Sb}$, $^{146}\mathrm{Eu}$, and $^{210}\mathrm{Bi}$ is shared between a first strongly excited fragment and higher lying groups. The valence plus outer shell (${\ensuremath{\nu}}_{13/2}$\ifmmode\times\else\texttimes\fi{}\ensuremath{\pi}${\mathit{h}}_{11/2}$${)}_{12}^{\mathrm{\ensuremath{-}}}$ strength is tentatively identified in $^{122}\mathrm{Sb}$.
