Description:
[Physics] Data for GEANT 3.21 detector simulator
GEANT is a framework for simulating the passage of subatomic particles through matter, for instance, particle detectors. For maximum flexibility, GEANT simulations are performed by linking FORTRAN code supplied by the user with the GEANT library, then running the resulting executable. . This package includes neutron cross-section data for use by GEANT.
