 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
