High-spin states in the direct 12, 13C(α, p)15, 16N reactions

A study of the39K(α,p)42Ca reaction at 25 MeV bombarding energy

“…We take a twoneutron ( f ~) ~ configuration for the positive parity states and an ( f ~) ~( d ~/ ~) -three-particle one-hole configuration description for the negative parity states in 42Ca which are populated in the 39K(a,p)42Ca reaction. Using the same procedure as previously described for the 13C(a,p) 16N reaction [13], we arrive at the following expressions for the calculated cross sections : for the two different parity states. In the expressions above, 1 and j are the transferred orbital and total angular momenta, J is the total angular momentum of the final state, N is a normalization factor, Do is the zero-range interaction constant and (do/dn)#WUCK4,TSTRIP is either the result of a full microscopic calculation or of a cluster form factor calculation normalized to the radial integrals from TSTRIP.…”
