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.
