Compton Scattering in Newtonian Physics

[rpardo]

Homework Statement

Derive the equation non-relativistic equation for Compton scattering

(mc^2) [(1/E2)-(1/E1)]+cos(theta)-[((E1-E2)^2)/(2E1E2)]=1

E1 = Incident Photon's energy
E2 = Scattered Photon's energy
theta= scattering angle
m = mass of electron
c = s

Here is the lab
In other words derive equation 2

Homework Equations

Conservation of Energy,conservation of mass, cosine law

The Attempt at a Solution

I've derived the first equation on the lab (relativistic approach)
I am really stumped on how to derive this...its been 4 hours and counting...
Any help at all would be appreciated. I feel like I'm really close but the algebra is the problem

Thanks in advance for your help guys and gals,

Truly appreciated

How did you set up the problem?

Here are some suggestions to make the algebra easier:

1. Write the kinetic energy of the electron as p^2/(2m).
2. Don't break the conservation of momentum equation into components.
3. Isolate the electron's momentum in the conservation of momentum equation on one side and then square the equation.
