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