Entrance Channel Versus Compound Nucleus Limitations in the Fusion Process of 1P and 2S-1D Shell Nuclei

摘要

The fusion process of two colliding nuclei occurs when the whole energy of the incident channel (potential and kinetic) is transformed into rotational and intrinsic energies of the compound nucleus. In last few years studies were undertaken to try to discriminate between entrance channel and compound nucleus effects in limiting the fusion cross sections (sigma fus). In this report one will present a large body of data from Saclay and elsewhere, describing only their essential features. Before to discuss the fusion cross section limits in the framework of the currently available models, one will present the experimental procedure to obtain and to reduce the data as well as problems related to the definition of fusion events at high energies.
