0063 // Provides functions to calculate the nuclear radius as used in the
0064 // abrasion-ablation model (see Wilson, Tripathi, Cucinotta et al, NASA
0065 // Technical Paper 3533, October 1995), and to determine total nuclear-nuclear
0066 // cross-sections.  The Algorithm comes from Tripathi, Cucinnota and Wilson,
0067 // Nucl Instrum Meth Phys Res B, 152, pp425-431, 1999.
