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.
