I have a degree in Physics, but it is only a Bachelors degree, and I specialized integrated circuit design and testing. But, I thought I understood the Bohr model of the hydrogen atom, and that said that in the ground state of the hydrogen atom, the deBrogelie wavelength of the electron matches one orbit. How one could get an orbit that is sub-wavelength does not make sense to me. I know that this is using classical reasoning. But the quantum mechanics model has the same answer. I would think that if such an atom exists, we should be able to create and measure it in the laboratory. Why has this not happened?
