Nature of problem:
The code calculates in a semimicroscopic way the bare interaction potential between a spherical nucleus and a deformed but axially symmetric one as a function of the center of mass distance as well as of the angle between the axis of symmetry of the target nucleus and the beam direction. 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.
The nucleus-nucleus potential is calculated using the double folding model with the Coulomb and the effective M3Y NN interactions. For the direct parts of the Coulomb and the nuclear terms, the Fourier transform method is used. In order to calculate the exchange parts the density matrix expansion method is applied.
Using a PC with 1.60 GHz processor under Windows XP less than 1 minute in the case of reduced calculations and about 40 minutes in the case of full calculations for one value of angle. Using Apple computer under MacOS the code runs by factor of 5 faster.
