Notes

This quantity is not exactly defined. It is given approximately for nuclei in their ground state by:

R = r_{0} A^{1 / 3}

where

$r_{0} \approx 1.2 \times 10^{- 15} unitsml(m)$ , and $A$ is the nucleon number (nucleon number).

Nuclear radius is usually expressed in femtometres, $1 unitsml(fm) = 10^{- 15} unitsml(m)$ .

Cette grandeur n'est pas exactement définie. Pour les noyaux dans leur état fondamental, elle est donnée approximativement par:

R = r_{0} A^{1 / 3}

où

$r_{0} \approx 1.2 \times 10^{- 15} unitsml(m)$ , et $A$ est le nombre de nucléons (nucleon number).

Le rayon nucléaire est habituellement exprimé en femtomètres, $1 unitsml(fm) = 10^{- 15} unitsml(m)$ .
