3. DESCRIPTION OF PROGRAM OR FUNCTION

AND is designed to obtain reliable atomic number densities for neutronic calculation by the use of well established physical constants (Avogadro number, atomic  mass, material density) and theoretical and experimental formulas.

4. METHOD OF SOLUTION

The theoretical formulas are employed to calculate number densities, except hydrogen number density in solutions where the formulas obtained by experiments are utilized.
