Nature of problem:
Collisions between two heavy nuclear systems give rise to a wide variety of phenomena. These include elastic, quasielastic, deep inelastic and fusion processes. The characteristics of these regimes are determined by an interplay between the relative motion of the two ions and the relevant internal degrees of freedom. Calculations of reaction cross sections with TORINO incorporate the explicit coupling to collective surface modes, which are treated as damped harmonic modes. The statistical exchange of nucleons between the reaction partners is also taken into account.
The different degrees of freedom are represented by classical variables whose evolution is followed by solving a system of first order coupled equations. The quantal character of the surface degrees of freedom is taken into account by constructing semiclassical distributions in phase space from a set of initial conditions which are consistent with the ground state wavefunctions of these modes. For the integration of the equations of motion, use is made of the NAG library. Results of the calculations are displayed in tables and plots which are produced by the CERN-library packages HBOOK and HPLOT.
