Hi,
I have heard someplace in my graduation course that two gamma photons are not allowed to yield a pair of particle anti-particle unless there is some material agent nearby. I remember also that this result was told to be very easy to demonstrate. Unfortunatelly there is no room for that in this page (recalling Fermat..).
Is there anyone who knows this proof ?
Thankx
