0f_7/2 proton transfer on ⁵⁵Mn

Proton pickup data have been obtained through the ⁵⁵Mn(d,³He)⁵⁴Cr (E_d = 46 MeV) reaction in the 6°–30° angular range using a magnetic spectrometer with a resolution of ∼ 40 keV full width at half maximum. Spectroscopic factors associated with transitions to 24 ⁵⁴Cr final states (E^*≤ 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 0f_7/2 proton transfer data has been performed using complementary stripping data from a study of the ⁵⁵Mn(α,t)⁵⁶Fe reaction. The 0f_7/2 proton transfer data have also been compared to results from a 0f1p shell-model calculation based on a new effective interaction for A = 41–66 nuclei. © 1996 The American Physical Society.
