Some time ago it was pointed out by Siems-sen et al. [l] that apparently the (d,n) spectroscopic factors for T, analogue states in the odd-odd nuclei FOB, I4N and 26~1 are a factor 2 to 3 smaller than those derived from (3He, d) experiments. Tamura [2] made some coupled-channel calculations in which the conventional DWBA amplitude was modified to include charge exchange coupling between (d, p) and (d, n) channels. These CC + DWBA calculations gave much reduced theoretical cross sections for the (d, n) reaction and apparently removed the discrepancy in spectroscopic factors. Subsequently it was found [3] that this result was incorrect and arose from a computational error. Actually the CC + DWBA cross sections turn out to be a little bit larger, thereby further increasing the discrepancy. Thus if the experimental effect pointed out by Siemssen et al. is real, no theoretical explanation is presently available. This makes it even more important to see if the experimental effect persists in heavier nuclei for which optical potentials and DWBA analyses are known to be more reliable. In this letter we report on results of a 54Fe(d,n)55Co experiment done at the Oak Ridge National Laboratory time-of -flight facility as a * Research sponsored by the U.S. Atomic Energy Commission under contract with Union Carbide Corporation. ** Oak Ridge Graduate Fellow from Northwestern Uni-versity under appointment from Oak Ridge Asso-ciated Universities, Inc.

N2 - Results of an experimental investigation of 54Fe(d, n)55Co reaction are presented and spectroscopic strengths for both T< and T> states are derived. It is concluded that within the limits of experimental and analytical uncertainties there is no discrepancy between the spectroscopic factors for T> analogue states as derived from the (d, n) and (3He, d) reactions.
