26 // class description
27 //
28 // This class is an interface to G4StaticSandiaData.
29 // it provides - Sandia coeff for an element, given its Z
30 // - sandia coeff for a material, given a pointer to it
31 //
32 // History:
33 //
34 // 10.06.97 created. V. Grichine
35 // 18.11.98 simplified public interface; new methods for materials. mma
36 // 30.01.01 major bug in the computation of AoverAvo and in the units (/g!)
37 // in GetSandiaCofPerAtom(). mma
38 // 03.04.01 fnulcof[4] added; returned if energy < emin
39 // 05.03.04 V.Grichine, new methods for old sorting algorithm for PAI model
40 // 21.21.13 V.Ivanchenko, changed signature of methods, reduced number of
41 // static variables, methods
42 //
