Projectile structure effects in multi-nucleon and cluster transfers in 16,18O+164Dy, 208Pb reactions

Abstract

The yield of projectile like fragments (PLFs) has been measured in the reactions of 16,18O with 164Dy and 208Pb targets at energies above the Coulomb barrier. The experimental data are analyzed to ascertain the role of projectile structure on the multi-nucleon and cluster correlations in transfer reactions. The variation of transfer probability with the number of nucleons transferred from the projectile to the target nucleus at the grazing angle has been investigated for both the systems. In the case of 18O induced reactions the cross sections of the two neutron (2n) stripping as well as the 2n- correlated cluster transfer are strongly enhanced as compared to the 16O induced reactions. These results have been discussed on the basis of the possible influence of the valence di-neutrons in the 18O nucleus on multi-particle transfer reactions. © Published under licence by IOP Publishing Ltd.
