Question Unusual interaction length number 

Forum: Physics List
Date: 13 Jan, 2010
From: Christopher Lirakis <Christopher Lirakis>

This seems odd. When I add the material the interaction length is correct, however on the verbose dump I get:

G4VDiscreteProcess::PostStepGetPhysicalInteractionLength [ PhotonInelastic]
 Particle type - gamma
   mass:        0[GeV]
   charge:      0[e]
   Direction x: 0, y: 0, z: -1
   Total Momentum = 4e-05[GeV]
   Momentum: 0[GeV], y: 0[GeV], z: -4e-05[GeV]
   Total Energy   = 4e-05[GeV]
   Kinetic Energy = 4e-05[GeV]
 MagneticMoment  [MeV/T]: 0
   ProperTime     = 0[ns]
 in Material  Air
InteractionLength= 1.79769e+307[cm]

Seems a bit crazy.
