Mechanism of theNe22(d,Li6)O18reaction

Abstract

As part of a systematic study, the (d,$^{6}\mathrm{Li}$) reaction has been measured at a bombarding energy of 80 MeV on $^{22}\mathrm{Ne}$. Angular distributions were obtained in an angular range of 8\ifmmode^\circ\else\textdegree\fi{} to 35\ifmmode^\circ\else\textdegree\fi{} (lab). In the framework of finite-range distorted-wave Born approximation calculations, alpha spectroscopic factors were extracted. The strong collectivity of the low-lying states suggests the necessity of employing a coupled reaction channels formalism in the analysis. Indeed spectroscopic information arising from one-channel distorted-wave Born approximation calculations reveals significant differences between experimental and theoretical results. Furthermore, the shapes of some experimental angular distributions are not fitted by the distorted-wave Born approximation method. Both give indications of an insufficiency of the simple one-channel calculations---at least for strong collective states.
