The transfer of a single nucleon in heavy ion reactions involving N14 has been studied quite intensively. The results are consistent with a mechanism involving tunneling through the Coulomb barrier of nucleons Coulomb-excited to virtual levels. This Letter concerns some studies of high-energy reactions in which several nucleons are transferred. Such reactions were found to be quite prominent and imply the existence of an important new mechanism for transfer reactions.
