63 // Provides functions to calculate the nuclear radius as used in the
64 // abrasion-ablation model (see Wilson, Tripathi, Cucinotta et al, NASA
65 // Technical Paper 3533, October 1995), and to determine total nuclear-nuclear
66 // cross-sections. The Algorithm comes from Tripathi, Cucinnota and Wilson,
67 // Nucl Instrum Meth Phys Res B, 152, pp425-431, 1999.
