Abstract

Angular distributions have been measured for the 54Fe(7Li, 6Li/6He)55Fe, 55Co reactions at E(7Li) = 48 MeV. Exact finite-range DWBA calculations for both reactions, employing Woods-Saxon real and imaginary potentials to generate the distorted waves, reproduce the shape of the f-state angular distributions but not the rate of fall-off with increasing angle for p-states. Using real potentials constructed by double-folding a microscopic nucleon-nucleon potential with a Woods-Saxon shaped imaginary potential to generate the distorted waves did not change the calculations. The forward angle (7Li, 6He) data allowed the 2p12 states in 55Co to be located and the determination of the single-particle centroid energies. The 55Co spectroscopic factors are in good agreement with those from the (d, n) reaction but are generally 25 % lower than those from average (3He, d) results. The 55Fe spectroscopic factors are in good agreement with (d, p) results.
