Abstract

The (p, t) reaction on 54Fe has been studied at Ep = 51.9 MeV with a broad-range magnetic spectrometer. States of 52Fe up to an excitation energy of 6.98 MeV are identified. Angular distributions are obtained for eighteen triton groups, and analysed in terms of distorted-wave Born approximation (DWBA) theory. It is found that the first-order finite-range correction improves calculated angular distribution shapes. New Jπ assignments, based on the DWBA calculation and on empirical angular distribution shapes, are proposed for several states. Transition strengths are compared with a shell-model calculation. Predicted strengths are found too large for higher-J states. A more elaborate method of two-nucleon form factor derivation is necessary to extract quantitative information on nuclear structure.
