// GEANT4 class header file

|
|
// Class Description:
|
|
// A clipboard for communicating between quantum entangled photons
|
|
// from e+ annihilation. Applies only to the two-gamma decay from the
|
|
// JP=0- state of e+e-, para-positronium. (This is the dominant process
|
|
// in materials such as human tissue, since the ortho-positronium JP=1-
|
|
// state, initially more likely, is "picked off" by a near-by electron
|
|
// and turned into para-positronium, because it has the much shorter
|
|
// meanlife.)
|
|
// Also applies to pi zero (JP=0-).
