Re: None a question on NeutronHPFission model... (Victor_Makarov)

I examined G4NeutronHPFissionFS. Lines

G4double time = -std::log(G4UniformRand())/theDecayConstants[i0-Prompt];

time += theTrack.GetGlobalTime(); (!)

seem to calculate delayed neutrons' time correct if I print out time variable. It gives values about 0.1 - 100 sec which agree with experimental data. But when I do /tracking/verbose 2, I see that tracks of delayed neutrons begin at GlobalTime which was used in formulae (!), so that -std::log(G4UniformRand())/theDecayConstants[i0-Prompt] part of sum has not been taken into account. This starting global time of a delayed neutron track is about nanosecond. I wonder, why is the time variable incorrectly proccessed? Or maybe I've got it all wrong?
