Probability Density Distribution for Electron Scattering

This Demonstration shows the scattering of the quantum-mechanical probability distribution for a particle scattered by a rigid cylinder, starting from a Gaussian state. Interference phenomena are exhibited as the number of time steps is increased.

To solve this Schrödinger equation, we use the finite-difference Crank–Nicolson method, incrementing the time variable in steps of .
