Three-particle cluster structure above E-x=11 MeV in N-15 - art. no. 024317

C-12(Li-7,alpha) angular distributions have been obtained for 16 states in N-15 at E(Li-7) = 52.5 MeV. Also, C-12((6)<(Li)over right arrow>,He-3) angu lar distributions and vector analyzing powers have been measured at E((6)<( Li)over right arrow>) = 50 MeV. Finite-range distorted-wave Born-approximat ion (FRDWBA) triton cluster transfer calculations are able to describe the (Li-7,alpha) data for transfer to states with known J(pi) values. Compariso n with known levels in F-19 suggests that the C-12(Li-7,alpha) reaction sel ectively populates negative parity states. FRDWBA calculations support this idea. Several previously suggested J(pi) levels are confirmed and new J(pi ) values are proposed for six other levels. The previously observed ((6)(Li )over right arrow>,He-3) J dependence has been used dong with coupled-chann el Born-approximation calculations to confirm the J(pi) values for states i n N-15.
