// Class Description
// Implementation of Kox formulas 
// Kox et al. Phys. Rev. C 35 1678 (1987); 
// Total Reaction Cross Section for Nucleus-nucles reactions.
//
// Class Description - End
// 18-Sep-2003 First version is written by T. Koi
// 12-Nov-2003 Set upper limit at 10 GeV/n
// 12-Nov-2003 Insted of the lower limit, 
//             0 is returned to a partilce with energy lowae than 10 MeV/n 
// 19-Aug-2011 V.Ivanchenko move to new design and make x-section per element
