I'm having some difficulty in working with units of mass at the quantum level. This difficulty most clearly manifests itself when I'm doing a Compton scattering problem.
Recall that Compton scattering is given by
[tex]\Delta \lambda =\frac{h}{m_{e}c}(1-cos(\theta ))[/tex]
and that the rest mass of an electron is 5.11 x 10^5 eV/c^2
My confusion seems to come about in the denominator. I find myself unsure of whether to multiply by c, c^2, or maybe something else entirely. In any case, for my problem, I keep getting the wrong answer, regardless of my method of attack.
If anyone could shed any insight on my problem, and also give me a big picture of relativistic units (i.e., here is how to handle relativistic units in calculations), it would be very much appreciated.
