[QUOTE="unscientific, post: 4970871, member: 54758"] [h2]Homework Statement [/h2] Given incoming photon has energy 10Mev and scatters at angle 25 degrees, find the scattering angle in CM frame.[ATTACH=full]175297[/ATTACH] [h2]Homework Equations[/h2][h2]The Attempt at a Solution[/h2] [/B] In lab frame, let the energy of incoming photon be ##E##. Total 4-vector would be ##P + Q = (\frac{E}{c},\frac{E}{c}) + (mc,0)##. Using [URL='https://www.physicsforums.com/insights/anatomy-of-compton-scattering/']compton scattering[/URL] formulas, I solved the scattering angle of electron ##\alpha = 35 ^o##, energy of scatted electron ##E_e = 4.02 ~MeV##, energy of scattered photon ##E' = 5.47~MeV##.Having solved this completely in the lab frame before/after scattering, how do I proceed in CM-frame? In CM frame, total momentum is ##0##, so 4-vector would be ##P_{cm} + Q_{cm} = (\frac{E_{p,cm}+E_{e,cm}}{c},0)##. Even when I assume that in CM frame they are both scattered along the same line it doesn't help. [/QUOTE]
