Particles and quantum waves diffusion in physical vacuum

The new quantum waves' diffusion equation based on Heisenberg uncertainties and De Broglie's frequencies of waves is presented. The free movement and quantum diffusion through a rectangular barrier are considered. We find a quantum diffusion coefficient and radii of bound systems. The obtained formula connecting radii and bound energies of simple quantum systems, such as a hydrogen atom, deuteron and mesons, consisted of quarks.
