Low Energy Reactions with Unstable Nuclei

Abstract

Several new ISOL radioactive nuclear beam facilities with post acceleration are coming into operation. The first experiments at REX-ISOLDE at CERN and SPIRAL at GANIL were made towards the end of 2001. Both facilities canre-accelerate beams of various radioactive nuclei to energies of about 2 MeV per nucleon and there are plans to increase this energy. Low energy beams with energies up to about 15 MeV per nucleon are very effective for studying reactions involving transfer of neutrons, protons or clusters of two or three nucleons. This contribution presents some simple formulae which are useful for estimating the energy and angular momentum dependence of transfer probabilities. They could be helpful in the design of experiments. The last part of the contribution is about a different topic: the calculation of pre-equilibrium gamma emission in heavy ion fusion reactions.
