Levels in /sup 38/K from the /sup 40/Ca(d,. cap alpha. ) reaction at 22. 8 MeV

Journal Article · · Phys. Rev. C; (United States)
Twenty levels in /sup 38/K up to an excitation energy of 10.26 MeV have been identified in a study of the /sup 40/Ca(d,..cap alpha..)/sup 38/K reaction at an incident deuteron energy of 22.8 MeV. Differential cross sections were measured at forty-four angles in an angular range 11/sup 0/< or =theta< or =165/sup 0/. Distorted-wave Born approximation analysis has been performed for eight transitions using two-nucleon spectroscopic amplitudes derived from a full sd shell-model calculation. For other levels, distorted-wave Born approximation calculations were performed assuming simple two-nucleon configurations. The 7.32-MeV level is found to be populated by L = 0+2 transfer and hence has J/sup ..pi../ = 1/sup +/. A newly identified level at 9.88 MeV is found to be excited by L = 2 transfer and hence has J/sup ..pi../ = 1/sup +/, 2/sup +/, or 3/sup +/.
