Warning Last Step missing in geant4.7.1p01 

Keywords: track step phot Kinetic energy geant4.7.1p01

Date: 28 Nov, 2005
From: Maria Lucia <lucia.magliozzi@iss.infn.it>

Dear G4 Users,

I'm running the same event (140 keV gamma) by g4.7.0 and g4.7.1p01. In the latter case, the KinE of the last step is not 0 as one should expect from the photoelectric effect, as actually is in the former case.

Any ideas?

Thank you in advance

MLucia
