// 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
|
|
// 15-Nov-2006 Change upper limit to 1 TeV/n
|
|
// However above 10GeV/n XS become constant.
|
|
// 23-Dec-2006 Isotope dependence added by D. Wright
|
|
// 19-Aug-2011 V.Ivanchenko move to new design and make x-section per element
