Criticism of Pound and Rebka experiment in light of Compton effect

Some relative scientists have reviewed my paper on refractional redshift and claimed that it is wrong because gammarays do not refract at all, as they are scattered by the helium, air, or both.

If that was true, then how does the gamma ray even reach the detector ?

Pound and Rebka used a bag of helium in order 'to minimise scattering’, and allow the gammaray to reach the detector, which was placed outside the helium bag, in air. But they dont wonder why they placed the detector in air, though, if they wanted to minimise scattering (air is much denser than helium). To me, it looks like they really wanted to get a refraction.

Or, if not a refraction, then a scattering from air. Because if there is any scattering of the gammarays then automatically they will be redshifted. This is called Compton scattering, and always results in a redshifted X-ray or gamma-ray. So I dont see how this helps their argument really. Even if there was no redshift from refraction, because of the Vasile effect, there was redshift from scattering, because of the Compton effect. And that is not a gravitational redshift either. Which means they confused gravitational redshift with Compton redshift. And that also proves that Einstein’s gravity theory is wrong.

So I dont know in how many ways do I need to disprove this stupid experiment until they realize that Einstein was wrong ?
