(. cap alpha. ,d) reaction on /sup 12/C and /sup 13/C and weak coupling configurations

Journal Article · · Phys. Rev. C; (United States)
Cross sections for the (..cap alpha..,d) reaction on /sup 12/C and /sup 13/C were measured at E/sub ..cap alpha../ = 34.9 MeV in the range of excitation energies up to 11 MeV in /sup 14/N and up to 13 MeV in /sup 15/N. The angular distributions were compared to calculations with the zero-range distorted-wave Born approximation with the assumption of a deuteron-cluster transfer. On the basis of the assumption that the transferred two nucleons are weakly coupled to the target nuclei, correspondences between the transferred angular momenta and the strengths for the two-nucleon pairs were found for the residual nuclei /sup 14/N and /sup 15/N. Effects of the 0d/sub 3/2/ shell and a necessity for the tensor force are discussed in terms of the two-nucleon configurations d/sub 3/2/p/sub 1/2/ and (d/sub 5/2/)/sup 2/, respectively.
