Homework Statement
Gamma rays of energy 1.02MeV are scattered from electrons which are initially at rest. Find the angle for symmetric scattering at this energy. What is the energy of the scattered photon from this case?
Homework Equations
[itex]\Delta[/itex] [itex]\lambda[/itex] = 0.0243A (1 - cos [itex]\theta[/itex] )
The Attempt at a Solution
What's throwing me off on this problem is the use of the gamma energy (1.02MeV). I'm perfectly equipped to handle this problem given wavelengths. Do I need to go back and calculate out the wavelength from conservation of energy? Any hints in the right direction are much appreciated.
Thanks.
