Abstract
The transfer of fast nucleons between two ions is investigated as a possible source of preequilibrium emissions. The transferred intensities are given by the tunnelling of a semi classical nuclear matter distribution through the potential barrier. The calculations predict proton-to-neutron ratios larger than one (1.35 for40Ca+40Ca), linear increases of the multiplicities with the incident energy; the results show too that the flow resulting from the overlap of the frozen density tails cannot account for the characteristics of the tunnelling flow.
