difference between the mass of an atom, and the product of its mass number and the unified mass constant:
where
:: is the rest mass (rest mass) of the atom,
:: is its nucleon number (nucleon number), and
:: is the unified atomic mass constant (unified atomic mass constant)

différence entre la masse d'un atome et le produit de son nombre de masse et de la constante unifiée de masse atomique:
où
:: est la masse au repos (rest mass) de l'atome;
