j-dependence of l = 1 transitions in the 54Cr(d, p) 55Cr reaction

Abstract

Differential cross sections for six l = 1 transitions in the reaction 54Cr(d, p)55Cr have been measured at a deuteron bombarding energy of 8 MeV. The data have been described qualitatively by DWBA calculations employing spin-orbit terms in the deuteron and proton optical model potentials to reproduce the observed dependence on j. Spin assignments of 3 2, 1 2, 3 2, 1 2 and 1 2 have been made for the ground, 0.245, 0.573, 1.487 and 2.905 MeV states in 55Cr. The 2p 1 2 and 2p 3 2 spectroscopic factor sums were found to be 0.66 and 0.56 respectively indicating a large admixture of (2p 1 2)2 configurations in the ground state of 54Cr. Show more
