How do anti-photons behave?

I have read much material stating that anti-photons do not exist, or that they must exist since quantum theory calls for a counter point to each particle -yet photons are their own anti particle…in any case, I came across one researcher who claims that when anti-photons interact with electrons, they do the exact opposite of photons. Anti photons make electrons jump down an electron orbital level, and then they jump back up to their original orbital layer, releasing two normal photons in the process.

Normally, photons make electrons jump up one electron orbit, where they then go back down to their original orbit, releasing photons in the process.

If this is true (the researcher does not claim to be a formal scientist), then I must ask:

What theoretically happens when a anti photon hits an electron in the lowest electron orbital cloud…? Does this layer one electron bump up against the atom’s nucleus? What happens then? If there is any truth to this, it is more theoretically possible with simpler elements that do not have complex electron orbital structures (hydrogen, helium).
