Programming language: Fortran-90. | ||

Computer: Any Unix/Linux workstation or PC with a Fortran-90 compiler. | ||

Operating system: Linux or Unix. | ||

RAM: 10 MB | ||

Keywords: Complete fusion cross section, Incomplete fusion cross section, Breakup cross section, Spin distribution, Kinetic energy distribution, Relative energy distribution, Angle distribution, Classical trajectory, Monte Carlo sampling. | ||

PACS: 25.60.Pj, 25.60.Gc, 25.60-t, 24.10.-i. | ||

Classification: 16.9, 17.7, 17.8, 17.11. | ||

Nature of problem:The program calculates a wide range of observables in reactions induced by weaklybound two-body nuclei near the Coulomb barrier. These include integrated complete and incomplete fusion cross sections and their spin distribution, as well as breakup observables (e.g. the angle, kinetic energy, and relative energy distributions of the fragments). | ||

Solution method:All the observables are calculated using a three-dimensional classical dynamical model combined with the Monte Carlo sampling of probability-density distributions. See Ref. [1,2] for further details. | ||

Restrictions:The program is suited for a weakly-bound two-body projectile colliding with a stable target. The initial orientation of the segment joining the two breakup fragments is considered to be isotropic. | ||

Additional comments:Several source routines from Numerical Recipies, and the Mersenne Twister random number generator package are included to enable independent compilation. | ||

Running time:About 75 minutes for input provided, using a PC with 1.5 GHz processor. | ||
