THE SM-154(SI-28, MG) AND SM-154(O-16, C) REACTIONS AT E/B APPROXIMATELY 1.6

The Sm-154(Si-28, Mg) and Sm-154(O-16, C) transfer reactions at E/B approximately 1.6 have been studied by means of fragment-gamma-ray coincides. Gamma-ray spectra are dominated, for both reactions, by the yrast transitions from Gd-156,Gd-154. The analysis of the energy loss spectra associated with Gd-156,Gd-154, performed in the framework of a model for transfer reaction and the statical model for the sequential evaporation, suggests that the two Gd isotopes are produced by different reaction mechanisms. The analysis of gamma-ray discrete lines for Gd-156 reveals different paths in the decay of excited primary products of the transfer reactions. The gamma-ray multiplicities are unexpectly similar for the two reactions. The complexity of the transfer processes is underlined.
