**Physics, Astronomy & Cosmology / Re: Does the atomic nucleus have nuclear orbitals occupied by protons and neutrons?**

Lets look at this a slightly different way. Electron orbitals are just the shape that the wave function of the electron takes on when bound to a nucleus. Therefore if the wave function of the electron is real then the electron orbitals should also be real. It would take some serious evidence to show the opposite.

There are certainly reasons to believe that the wave function is real.

At best you can say that according to some interpretations of Quantum Mechanics the wave function isn't "real/physical" but the question is unsettled. Although there is evidence pushing for the real camp.

Additionally,

The phase of a wave function (the complex bit) can have physical effects beyond just participating in the squared magnitude (the extra rotation of the photons in the link).

You can make qubits by exploiting the phase (imaginary) parts of wave functions.

The things above and others like single particle diffraction and tunneling are less strange if you simply accept that the wave function is real.

But to reiterate one should never state as fact that the wave function is not real. At best the question is exactly as unsettled as the question about which interpretation is correct with a bit of evidence pulling for the wave function is real camp.

It was atomic hydrogen. You can break a fraction of hydrogen molecules apart and keep that fraction constant by adding energy so more are broken at the same rate others reform. Then you can build a trap big enough for only one atom and eventually if you wait long enough you'll have a trapped hydrogen. If you keep the gas dilute enough collisions between things will be very rare.

What is the form of hydrogen used in the experiment? Is atomic or molecular?

If it is atomic, how to prevent them from forming diatomic molecule?

If it is molecular, how can it produce rotationally symmetrical pattern?
