NUCLEAR CLUSTERS IN EXIT AND ENTRANCE CHANNELS

The exit and entrance channels leading rapidly from one sphere to two spheres and vice versa assuming volume conservation and neck formation in keeping quasi-spherical shapes have been investigated. The potenti al energy has been determined within a liquid drop model including an accurate radius, a proximity energy, the mass asymmetry and the temper ature. The calculated fission and fusion barrier characteristics, half -lives of radioactive nuclei emitting heavy clusters, fragment kinetic energies, critical angular momenta of light nuclei and rotating super and hyperdeformed state properties are compatible with the available experimental data.
