0023     \brief This class is for no beam spectra, i.e. monochromatic beams.
0024     In the unpolarized case, the weight will be exactly one, otherwise it should be
0025     given by
0026     \f[
0027     {\cal W} = \frac{\lambda_{\rm in}+\lambda_{\rm out}}{2}\,,
0028     \f]
0029     where both \f$\lambda_{\rm in,out}\f$ are the polarization degrees of the incoming
0030     and outgoing particle.
0031     \todo This is still to be implemented !
