Coulomb-nuclear interference for the (d, d′) reaction on isotopes of Nd

Abstract

Excitation functions at 140\ifmmode^\circ\else\textdegree\fi{} laboratory angle have been measured for inelastic deuteron scattering to the first ${2}^{+}$ states of $^{142,144,146,148,150}\mathrm{Nd}$. The anomalous destructive Coulomb-nuclear interference previously observed for other $N=82$ isotones also occurs for $^{142}\mathrm{Nd}$. This anomaly is seen to be a sudden change in the nature of the interference rather than a gradual change as one approaches this closed shell.NUCLEAR REACTIONS $^{142,144,146,148,150}\mathrm{Nd}(d, {d}^{\ensuremath{'}})$, $E=5\ensuremath{-}16$ MeV; measured $\ensuremath{\sigma}(E)$ at ${\ensuremath{\theta}}_{\mathrm{lab}}=140\ifmmode^\circ\else\textdegree\fi{}$. Deduced deformation parameters ${\ensuremath{\beta}}_{2}$. Enriched targets.
