Journal reference: Comput. Phys. Commun. 175(2006)372 | ||

Programming language: Fortran-77. | ||

Computer: The code has been created on an IBM-PC, but also runs on UNIX or LINUX
machines. | ||

Operating system: WINDOWS or UNIX. | ||

RAM: 16 Mbytes of RAM memory and 2 MB of hard disk space | ||

Keywords: Momentum distributions, Breakup, Stripping, Diffraction dissociation. | ||

PACS: 25.60.Gc, 24.50.+g, 25.60.-t. | ||

Classification: 17.11, 17.19. | ||

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. | ||

Solution method: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. | ||

Running time: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. |
