2-Nucleon, 3-Nucleon And 4-Nucleon Transfer, Doorways To Fusion

Near-barrier differential cross sections of the prominent transfer channels in the systems S-33, Zr-90, Zr-91, Zr-93 and S-32 , Ru-100, Ru-101 have been measured including Q-distributions. The relatively large 2-,3- and 4-nucleon transfer cross sections suggest their contribution to the observed fusion enhancements. The angular distributions are discussed within the frame work of a simple semiclassical formalism and some interesting connections to fusion are revealed.
