Thank you smile emoticon I’ve actually tried looking into that question you asked as well. I had a result too somewhere. Somehow I think it was 37 degrees for some reason but this was about 2 yrs ago that I was looking into that.
For some odd reason it was very important for me to get some kind of answer; what angle does a photon leave an electron?
I remember looking into optimum gravitational escape angles… some stuff on refraction properties … man, I gotta go through my notes now. I was on a kick, but once I leave intensely looking into a subject, I move onto the next one, and details start to dim.
