Nature of problem:
The program calculates double folded potentials for use in nuclear scattering problems by integrating a nucleon-nucleon interaction over the density distributions of the two colliding nuclei. Potentials for elastic, inelastic and other scattering processes may be generated by appropriate choice of the interaction and the densities. In addition to a wide range of density independent interactions, a restricted class of density dependent interactions may also be employed.
The potential is calculated by making multipole expansions of the densities and performing the integration in momentum space by a Fourier transform technique.
The program has been written to be very general with few restrictions The main restriction is that only a limited type of density dependent interactions may be used. Other minor restrictions are described fully in the long write-up.
Using the IBM H-compiler the test calculation described in section 6 of the long write-up took 16.6 s to compile, 0.4 s to link-edit and 2.1 s to execute.
