NAME
Chemistry::Isotope - Table of the isotopes exact mass data
SYNOPSIS
use Chemistry::Isotope 'isotope_mass';
my $m = isotope_mass(235, 92); # 235.043923094753DESCRIPTION
This module contains the exact mass data from the table of the isotopes. It has a single exportable function, isotope_mass, which returns the mass of an atom in mass units given its mass number (A) and atomic number (Z).
The table includes masses for 2931 nuclides and is taken from http://ie.lbl.gov/txt/awm95.txt (G. Audi and A.H. Wapstra, Nucl. Phys. A595, 409, 1995)
FUNCTIONS
isotope_mass($A, $Z)
Return the mass for the atom with the given mass number and atomic number, or undef if the nuclide is not in the data table.
