0026 // class description
0027 //
0028 // This class is an interface to G4StaticSandiaData.
0029 // it provides - Sandia coeff for an element, given its Z
0030 //             - sandia coeff for a material, given a pointer to it
0031 //
0032 // History:
0033 //
0034 // 10.06.97 created. V. Grichine
0035 // 18.11.98 simplified public interface; new methods for materials.  mma
0036 // 30.01.01 major bug in the computation of AoverAvo and in the units (/g!)
0037 //          in GetSandiaCofPerAtom(). mma
0038 // 03.04.01 fnulcof[4] added; returned if energy < emin
0039 // 05.03.04 V.Grichine, new methods for old sorting algorithm for PAI model
0040 // 21.21.13 V.Ivanchenko, changed signature of methods, reduced number of
0041 //                        static variables, methods
