Nature of problem:
This computer code calculates the cross sections of various reactions for a core plus one valence-nucleon system in the framework of the Glauber model. The examples of calculation include the reaction cross sections for 13,19C+12C, the elastic differential cross section for 11Be+12C and the momentum distribution of the core nucleus for 11Be+9Be and 8B+12C systems.

Solution method:
The scattering amplitude is formulated in the Glauber theory. The phase-shift functions between the core and the target and between the valence nucleon and the target are calculated in the optical-limit approximation. The integration over the valence-nucleon coordinates is performed by Monte Carlo integration, while the integration over the impact parameter is done with a trapezoidal rule.

The projectile nucleus is assumed to be a core plus one valence-nucleon system, in which the valence nucleon is described with a pure configuration. The projectile is assumed to have no particle-bound states except for its ground state. The nucleon-nucleon profile function is assumed to have one-range Gaussian form or zero-range delta function. The core and target densities have to be fit in terms of a combination of Gaussians. The breakup due to the Coulomb interaction is neglected.

Running time:
For the sample calculations shown in text, the computer time is as follows: 5 min for the total reaction cross section, 5 min/point for the elastic differential cross section, and 10 min/point for the momentum distribution.
