Abstract We present a C-code designed to obtain the nucleus–nucleus potential by using the double folding model (DFM) and in particular to find the Coulomb barrier. The program calculates the nucleus–nucleus potential as a function of the distance between the centers of mass of colliding nuclei. The most important output parameters are the Coulomb barrier energy and the radius. Since many researchers use a Woods–Saxon profile for the nuclear term of the potential we provide an option in our code for f... Title of program: DFMSPH Catalogue Id: AEFH_v1_0 Nature of problem The code calculates in a semimicroscopic way the bare interaction potential between two colliding spherical nuclei as a function of the center of mass distance. The height and the position of the Coulomb barrier are found. The calculated potential is approximated by a conventional Woods-Saxon profile near the barrier. Dependence of the barrier parameters upon the characteristics of the effective NN forces (like, e.g. the range of the exchange part of the nuclear term) can be investigated.
