In-plane polarization transfer in the 6Li(p,p') reaction and the effective NN interaction.

Abstract

We have measured the in-plane polarization transfer coefficients for the $^{6}\mathrm{Li}$(p,p') reaction using a longitudinally polarized beam at 65 MeV. A microscopic distorted-wave Born-approximation analysis with the M3Y interaction has been performed for the excitation to the first ${0}^{+}$ state (T=1). The isovector tensor force ${\mathit{V}}_{\mathit{T}\mathrm{\ensuremath{\tau}}}$ and the isovector spin-orbit force ${\mathit{V}}_{\mathit{L}\mathit{S}\mathrm{\ensuremath{\tau}}}$ have been adjusted in order to reproduce the experimental differential cross sections, depolarization parameters, and in-plane polarization transfer coefficients. This analysis suggests that the high-momentum components of ${\mathit{V}}_{\mathit{T}\mathrm{\ensuremath{\tau}}}$ should be substantially reduced from the M3Y interaction and ${\mathit{V}}_{\mathit{L}\mathit{S}\mathrm{\ensuremath{\tau}}}$ needs to be more attractive.
