Excited state transfers in the C-12((6)(Li)over-right-arrow, alpha)N-14 reaction - art. no. 064607

The C-12((6)<(Li)over right arrow>,alpha)N-14 reaction cross section, and a nalyzing powers to the 2(+) (7.03 MeV) natural parity state of N-14 have be en studied by coupled reaction channels calculations that include deuteron cluster transfer from the 1(+) ground and 3(+),2(+),1(+) spin-orbit triplet excited states in Li-6 as well as from the first 2(+) excited state in C-1 2 to assess the role played by these inelastic transfers. This natural pari ty transition was chosen for detailed study because the number of L transfe rs allowed is more limited than for transfers to unnatural parity states. I nclusion of the transfer from the 1(+) excited state of Li-6 is especially vital for understanding the tensor analyzing power data T-21. The same anal ysis was then applied to the transfers to the 1(+) ground and 3.95 MeV stat es in N-14. Failure to describe the shape of the ground state angular distr ibution motivated its remeasurement and its anomalous shape was confirmed. The present work suggests that single nucleon sequential transfer might be the dominant mode for the ground state transfer.
