A nuclear fluiddynamical approximation with one-plus-two-body viscosity

A semiclassical fluiddynamical model based on an usual scaling approximation (SCA) is extended to investigate the role of one and two-body dissipation in the widths of nuclear collective modes. The competition between one and two-body viscosity in:i) the collisionless (elastic) limit;ii) the hydrody...
