0f7/2 proton transfer on 55Mn.

Abstract

Proton pickup data have been obtained through the {sup 55}Mn({ital d},{sup 3}He){sup 54}Cr ({ital E}{sub {ital d}} = 46 MeV) reaction in the 6{degree}{endash}30{degree} angular range using a magnetic spectrometer with a resolution of {approximately} 40 keV full width at half maximum. Spectroscopic factors associated with transitions to 24 {sup 54}Cr final states ({ital E}{sup {asterisk}}{le} 6.104 MeV) were determined from local, zero-range distorted-wave Born approximation analyses of the measured angular distributions allowing for l = 0, 1, 2, and 3 transfer. A spin-dependent sum-rule analysis of the 0{ital f}{sub 7/2} proton transfer data has been performed using complementary stripping data from a study of the {sup 55}Mn({alpha},{ital t}){sup 56}Fe reaction. The 0{ital f}{sub 7/2} proton transfer data have also been compared to results from a 0{ital f}1{ital p} shell-model calculation based on a new effective interaction for {ital A} = 41{endash}66 nuclei. {copyright} {ital 1996 The American Physical Society.}
