                  DFM-POT -  the program for calculation 
            of the double folding nucleus-nucleus potential

    The program DFM-POT calculates the double folding nucleus-nucleus potential
    of elastic scattering. The code is written on C++.  
    Input parameters are: atomic mass and energy of interacting nuclei,
    the interval length and the stepsize of numerical integration, 
    type of nucleon-nucleon potential. Beside, the nuclear density distribution
    is needed to be known for each of interacting nuclei.

    The density distribution function can be given in the table form or
    in the analytic form (Gaussian, Yukawa and Fermi functions). Two types
    of nucleon-nucleon potentials are available: Reid-Elliot potential 
    (M3Y-Reid) and Paris potential (M3Y-Paris).

    Simpson’s method is applied for numerical integration. Derivatives 
    in the formulas for local momentum are approximated by three-points
    finite-difference schemes.

    The calculation takes a few minutes for light nuclei and low energies.
    For heavy nuclei and energies about 1000-1500 MeV, the computational
    time is several hours at computer Pentium-IV. 

    The code DFM-POT was applied in [1-3] for calculation of microscopic
    nucleus-nucleus optical potentials. In [4,5] the code was generalized
    for inelastic. Description of the DFM method, iteration procedure and
    the code is given in [6].
    Demo version of the code is available at the site
    http://luky.jinr.ru/dfmpot/.
    for 6He + 28Si with Gauss and Fermi density distributions
    for 6He and 28Si, respectively, at energy 50 A MeV.
