Abstract

AN appraisal of nuclear reactions in heavy ion systems which are known to be of importance in nuclear astrophysical processes indicated that reactions involving transfer of α particles could be of significant strength and hence should be included in reaction network studies which lead to the prediction of stellar abundances, The heavy ion systems of interest are 16O + 16O, 12C + 16O and 12C + 12C. Preliminary results from a recent experiment (T. W. C., B. W. Hooton and G. Murray, to be published) have shown in the case of the 12C + 16O system that, at energies of astrophysical importance, the channel leading to 20Ne + 2α, which corresponds to the transfer on α particle, is of significant strength. This result influences predictions of the abundance of 20Ne and that of elements depending on 20Ne for their subsequent formation.
