Nuclear scattering theory describes interactions between projectile and target nuclei via differential cross-sections ($d\sigma/d\Omega$), which quantify the probability distribution of outgoing particles defined by energy, solid angle, and flux density within a spherically symmetric potential field. The formalism distinguishes reaction mechanisms based on interaction timescales and spatial extent: elastic Coulomb scattering occurs at low energies without overcoming the repulsive barrier, whereas inelastic processes involve direct reactions with peripheral nucleons or compound nucleus formation where the system equilibrates into an intermediate state before decay. These concepts constitute the fundamental framework of nuclear physics for analyzing dynamics ranging from Rutherford-type electrostatic deflections to high-energy heavy ion collisions that probe sub-nucleonic structures and fusion-fission energy release mechanisms.
