Abstract
The quantum scattering of wavepackets from a single slit and a double slit with the Schrödinger equation is studied numerically and analytically. The phenomenon of diffraction of wavepackets in space and time in the backward region previously found for barriers and wells is encountered here also. A new phenomenon of forward diffraction that occurs only for packets thinner than the slit, or slits, is calculated numerically as well as in a theoretical approximation to the problem.
