   $$\sigma_{geo} = \pi R^2$$
   However, in actual physical phenomena, such as nuclear reactions or scattering events, the interaction probability is not purely dependent on the physical dimensions but is modulated by quantum mechanical or relativistic effects, requiring the definition of an effective or interaction cross section. This deviation from simple geometry is crucial for distinguishing between elastic scattering, [inelastic sc…
