J dependence in the /sup 50/Cr(/sup 7/Li,/sup 6/He)/sup 51/Mn reaction at 28 MeV

Journal Article · · Phys. Rev., C; (United States)
;
The reaction /sup 50/Cr(/sup 7/Li,/sup 6/He)/sup 51/Mn was investigated at extreme forward angles, 1.6/sup 0/< or =theta< or =12/sup 0/, in order to study the j dependence for the (/sup 7/Li,/sup 6/He) reaction at 28 MeV. The /sup 6/He ejectiles were detected with a position-sensitive (helix) counter in the focal plane of an Enge-split-pole spectrograph. A total energy resolution of about 30 keV was obtained. The angular distributions for seven low-lying states in /sup 51/Mn show a pronounced j dependence for angles below 7/sup 0/ and the expected l dependence at angles theta> or =9/sup 0/. Finite-range distorted-wave Born-approximation calculations which include recoil effects reproduce the j-dependent angular distributions very well and permit a clear distinction between p/sub 3/2/, p/sub 1/2/, f/sub 7/2/, and f/sub 5/2/ final-state angular momenta. The relative spectroscopic factors deduced were in reasonable agreement with those obtained in a recent /sup 50/Cr(/sup 3/He,d)/sup 51/Mn reaction study.
