摘要
Relativistic and non-relativistic scattering by short-range potentials is investigated for selected problems. Scattering by the delta' potential in the Schrodinger equation and delta potentials in the Dirac equation must be solved by regularization, efficiently carried out by a perturbation technique involving a stretched variable. Asymmetric regularizations yield non-unique scattering coefficients. Resonant penetration through the potentials is found. Approximative Schrodinger equations in the non-relativistic limit are discussed in detail.
