Electron Diffraction at Multiple Slits

The American Journal of Physics published a translation of Claus Jonsson's paper "Electron Diffraction at Multiple Slits" in American Journal of Physics 42, 4-11 (1974). The following calculations are in agreement with the diffraction patterns reported by Jonsson.

Number of slits:

Slit width:

Slit locations:

Normalized coordinate-space wave function at the slit screen:

Fourier transform of the position wave function into the momentum representation:
