Final Lab Frame Moller Electron 4-momentum components in XZ Plane
Figure 3: Definition of Moller electron variables in the Lab Frame in the x-z plane.
Using [math]\theta '_2=\arccos \left(\frac{p^'_{2(z)}}{p^'_{2}}\right)[/math]
| [math]\Longrightarrow {p^'_{2(z)}=p^'_{2}\cos(\theta '_2)}[/math]
|
Checking on the sign resulting from the cosine function, we are limited to:
| [math]0^\circ \le \theta '_2 \le 60^\circ \equiv 0 \le \theta '_2 \le 1.046\ Radians[/math]
|
Since,
[math]\frac{p^'_{2(z)}}{p^'_{2}}=cos(\theta '_2)[/math]
[math]\Longrightarrow p^'_{2(z)}\ should\ always\ be\ positive[/math]
