// by J.P Wellisch, Sun Sep 15 2002.
// corrected G.Folger 17-8-2006: inel. Ca pim was missing two number, 
// + formatting
//
// updated   G.Folger 21-8-2006: Change scaling of cross section for 
// elements not tabulated from scaling in Z^(2/3) to A^0.75
// Implements P2-90-158;
//
// 22 Dec 2006 - D.H. Wright added isotope dependence
//
// 19 Aug 2011, V.Ivanchenko move to new design and make x-section per element
