Analyzing powers for theC12(6Li→,α)14N*reaction at 33 MeV

Angular distributions of the cross section and the first complete set of analyzing powers for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ ${(}^6$Li→,α${)}^{14}$N have been measured over the range 4°≤${\mathrm{\theta }}_{\mathrm{lab}}$≤29° at a bombarding energy of 33 MeV. The ${}_{}{}^{\mathit{T}}{}_{}{}^{}$ ${\mathit{T}}_{20}$ analyzing power data are shown to distinguish between natural and unnatural parity states in ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ as observed earlier in (d→,α) reactions. General rules are presented for tensor analyzing powers for transfers to $0^{\pm }$ and $1^{\pm }$ states that are derived assuming only conservation of parity and total angular momentum. Finite-range deuteron cluster transfer DWBA calculations which allowed coherent multiple L transfers were carried out and compared with the data. The analyzing powers exhibited sensitivity to L mixing including the presence of D states in both ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ and ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ but had limited success in describing the data.
