ABSTRACT

A few processes have been used to populate high spin states in nuclei. Few-nucleon transfer reactions have been used for this purpose mainly in the light nuclei. The deep inelastic collisions also populate such states and may become the main source of such information in neutron-rich, unstable nuclei, which are not accessible, for this purpose, by other methods. Multiple Coulomb excitation is a rather important method, the potential of which increased very much during the last years, following the acceleration of very heavy nuclei. Thus, it can provide information on collective -y-ray transitions from states with spin up to 20 to 30 h. 1 It is restricted, however, to stable, deformed nuclei, and has been applied until now, mainly in the rare earth and actinide nuclei.
