Nuclear Radius
Nuclear radius scales as the cube root of mass number, implying constant nuclear density. R₀ ≈ 1.2 × 10⁻¹⁵ m (1.2 femtometers).
Variables
Rm
Nuclear radius
R_0m
Radius constant (≈ 1.2 fm)
Aunitless
Mass number (protons + neutrons)
Derivation
Empirically determined from scattering experiments; implies nucleons are incompressible.
