30 // Class Description
31 // Implementation of formulas
32 // Shen et al. Nuc. Phys. A 491 130 (1989);
33 // Total Reaction Cross Section for Heavy-Ion Collisions
34 //
35 // Class Description - End
36 // 18-Sep-2003 First version is written by T. Koi
37 // 12-Nov-2003 Set upper limit at 10 GeV/n
38 // 12-Nov-2003 Insted of the lower limit,
39 // 0 is returned to a partilce with energy lowae than 10 MeV/n
40 // 15-Nov-2006 Change upper limit to 1 TeV/n
41 // However above 10GeV/n XS become constant.
42 // 23-Dec-2006 Isotope dependence added by D. Wright
43 // 19-Aug-2011 V.Ivanchenko move to new design and make x-section per element
