6LI INDUCED REACTIONS ON 12C AT ELAB = 20 MEV

Differential cross sections for the reactions 12C(6Li, d)16O, 12C(6Li, α)14N and 12C(6Li, p)17O, were measured at Elab = 20 MeV. The angular distributions exhibit neither pure direct nor pure compound nuclear reaction mechanisms. It is assumed that the excitation of the 8.88(2-) MeV level in 16O is due to a pure compounf nuclear reaction. To estimated the compound nucleus contribution for some of the low-lying levels in 16O, Hauser-Feshbach calculations were carried out. The strong excitation of some rotational states in 16O can be explained by a good angular momentum match for a direct α-particle capture. A similar explanation fails for the states in 14N. © 1968.
