// Allison AtRest positron 2-gamma annihilation model

// Electron of media is assumed to have the Maxwell–Boltzmann
|

// distribution defined by the temperature of the media.
|
||
// Energy of mean ionisation should not be zero - some amount of free
|
||
// electrons should be in the media.

// Nature 4065 (1947) 435.
