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 2 p 1 2 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.
