A particle of initial kinetic energy T0 and rest energy E0 strikes a like particle at rest. The initial particle is scattered at an agle theta to its original direction. Show that the final kinetic energy T is(adsbygoogle = window.adsbygoogle || []).push({});

T = T0cos2(theta)/(1+ (T0sin2(theta)/2E0))

what I have so far:

We know that T = E - E0 and that four momentum will be conserved. Also I think if we choose a suitible invariant it may simplify the problem

Could I get more suggestions/hints a starting point etc.

Thanks

GM
