Do gamma and X-ray wavelength photons also exist as collapse able wave fx's?

This question has gone unanswered by our friends in nuclear/atomic threads.

My question relates to a solitary Tc^99m decay in particular, and to gamma rays in general. If light is a collapse able wave function, are different wavelength energies the same, ie gamma, x, radio, etc.

My suspicion is yes. Does this mean that a gamma photon detected from a far away galaxy is in fact the collapse of an ever expanding wave function?

Light is essentially the same thing as x-ray or gamma radiation at a lower energy, yes. But I don't think it has a "wavefunction" in any ordinary sense. The reason for this is that you can create and destroy billions of photons as easily as switching on and off a light bulb, so there's no conserved probability density for any individual photon. Instead, you have to think about a photon as the quantum of the electromagnetic field.
 
Photons are not destroyed by turning off a light, they are just no longer created. The emitted photons travel onward until acting upon something, no?

This is helpful, thank you

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
