Angular distribution measurements forC14(d, p)C15and the level structure ofC15

Abstract

A 14 MeV deuteron beam was used to measure the angular distributions for the $^{14}\mathrm{C}(d, p)^{15}\mathrm{C}$ reaction leading to the two bound states and eight of the unbound states of $^{15}\mathrm{C}$. Vector-analyzing powers were measured for the elastic scattering and for the two bound states. Distorted wave Born approximation calculations were performed and spectroscopic factors were obtained for the two bound states. Calculations for stripping to unbound states using a resonance form factor and following the approach of Vincent and Fortune were compared with the angular-distribution data of the unbound states to obtain values of $J$, $\ensuremath{\pi}$, and neutron width ${\ensuremath{\Gamma}}_{n}$. A strong $J$ dependence occurs in the calculated cross sections for stripping to unbound states.NUCLEAR REACTIONS $^{14}\mathrm{C}(d, p)$, ($\stackrel{\ensuremath{\rightarrow}}{d}, p$), ($\stackrel{\ensuremath{\rightarrow}}{d}, d$), ${E}_{d}=14.0$ MeV: measured $\ensuremath{\sigma}(\ensuremath{\theta})$, $i{T}_{11}(\ensuremath{\theta})$. $^{15}\mathrm{C}$ levels deduced $J$, $\ensuremath{\pi}$, $S$, and/or $\frac{{\ensuremath{\Gamma}}_{n}}{{\ensuremath{\Gamma}}_{\mathrm{s}.\mathrm{p}.}}$.
