Nature of problem:
The complete fusion cross section is calculated as a function of energy with a semiclassical friction free model. No allowance is made (1) for energy and angular momentum dissipation due to particle emission (e.g. 4He/1H,) prior to fusion and (2) for loss of low partial waves due to highly inelastic events. The cross section is calculated by partial wave summation. Barrier penetration is included and so is the l dependence of the fusion radius and the curvature of the barrier. The real potential may take a number of forms. Provision is made to alter parameters of nuclear and Coulomb potentials so that a best match to the experimental fusion barrier/cross sections can be achieved.

Solution method:
The real potential may take a number of forms. Provision is made to alter parameter of nuclear and Coulomb potentials so that a best match to the experimental fusion barrier/cross sections can be achieved.

Restrictions:
Calculations are straightforward and involve no complexity.

Running time:
Typical running time (CPU) on the UNIVAC 1100 is 2.475 s for tabulated form of the nuclear proximity function and slightly over 0.3 s for the other options and/or combination of options. Typical I/O time is about 1.7 s.
