Semiclassical calculations (high energy collisions)

Program to calculate differential Coulomb break up cross sections from external transition probabilities following [1] both in angle and energy. Multipolarities included are dipole and quadrupole for electric transitions and only dipole for magnetic transitions. Inelastic Coulomb cross section can also be calculated for the same multipolarities. Different options for convoluting cross sections with experimental resolution are provided. The effect of Nuclear absorption can be estimated by reading external S-matrix in the format of FRESCO output [2] as done in [3]. Applications of the present code can be found in Refs. [4-6].

FRESCO

Coupled Reaction Channels Calculation

Fresco is a program developed by Ian Thompson over the period 1983 - 2006, to perform coupled-reaction channels calculations in nuclear physics. Sfresco is an additional version of Fresco, to provide Chi-squared searches of potential and coupling parameters, and to fit additional R-matrix terms in hybrid models.
