 34 // Class Description: 
 35 //
 36 // Allison AtRest positron 2-gamma annihilation model
 37 // Electron of media is assumed to have the Maxwell–Boltzmann
 38 // distribution defined by the temperature of the media.
 39 // Energy of mean ionisation should not be zero - some amount of free
 40 // electrons should be in the media.
 41 // Polarisation of gamma according to M.H.L.Pryce and J.C.Ward, 
 42 // Nature 4065 (1947) 435.
 43 // Snyder et al, Physical Review 73 (1948) p.440.
