De Broglie's Wavelength of a Particle Has a Conflict — •Albrecht Giese — Taxusweg 15, 22605 Hamburg

The postulation of matter waves by Louis de Broglie was a big step towards a new understanding in particle physics and of quantum mechanics. And his result that the wavelength of a particle is given by the particle's momentum was convincing at the first glance and seemed to be confirmed by experiments.

Unfortunately, however, de Broglie's deduction of the wavelength is based on an incorrect understanding of special relativity. And the dependence of the wavelength on momentum is neither Lorentz- nor even Galilei-invariant. It does not therefore reflect correct physics. Nevertheless, it was used by Schrödinger and by Dirac as an essential part of their wave functions.

We will explain how the problem occurred and why the results seem to be confirmed by experiments. And we will show what a correct solution would look like.
