33 // by J.P Wellisch, Sun Sep 15 2002.
34 // corrected G.Folger 17-8-2006: inel. Ca pim was missing two number,
35 // + formatting
36 //
37 // updated G.Folger 21-8-2006: Change scaling of cross section for
38 // elements not tabulated from scaling in Z^(2/3) to A^0.75
39 // Implements P2-90-158;
40 //
41 // 22 Dec 2006 - D.H. Wright added isotope dependence
42 //
43 // 19 Aug 2011, V.Ivanchenko move to new design and make x-section per element
