Backscattered photon spectrum

This function describes the spectrum of photons scattered backward from the interaction of laser light with the high energy electron beam:


\begin{displaymath}f(x) = \left\{
\begin{array}{ll}
0, & \mbox{for~} x>x_{max} ...
..._0 (1-x)) \,))), & \mbox{for~} 0<x<x_{max}
\end{array} \right. \end{displaymath}

where $x_0=4.82, \; x_{max}=x_0/(1+x_0), \; N$ is a normalization factor.

The above spectrum corresponds to the special initial condition when unpolarized photons are created. See [Ginzburg-1983] for more details.
