// 05.03.04 V.Grichine, new methods for old sorting algorithm for PAI model

// 03.04.01 fnulcof[4] added; returned if energy < emin

// 30.01.01 major bug in the computation of AoverAvo and in the units (/g!)

|
// in GetSandiaCofPerAtom(). mma
|
|
// 18.11.98 simplified public interface; new methods for materials. mma
