Nature of problem:
The program calculates bound wavefunctions, eikonal S-matrices, total cross sections and momentum distributions of interest in nuclear knockout reactions at intermediate energies.
Solves the radial Schrödinger equation for bound states. A Numerov integration is used outwardly and inwardly and a matching at the nuclear surface is done to obtain the energy and the bound state wavefunction with good accuracy. The S-matrices are obtained using eikonal wavefunctions and the "t-ρρ" method to obtain the eikonal phase-shifts. The momentum distributions are obtained by means of a gaussian expansion of integrands. Main integrals are performed with the Simpson's method.
Almost all CPU time is consumed by calculations of integrals, specially for transverse momentum distributions which involves multiple integral loops. It takes up to 30 min on a 2GHz Intel P4-processor machine.
