Description jinyk03 2004-12-07 06:42:06 CET 
the physics used are G4RadioActiveDecay and all the hadronic/EM processes.

Firstly I input the proton(200MeV) to the Pb, the simulation will stop when the
isotope Ho163[0.0] or Tl194[0.0] is generated.

Then I just use any of these two isotopes to input, the simulation will also
stop.

I don't know why. Maybe something wrong with these two isotopes.

Dear Fan,  can you have a look? Greetings, Hans-Peter.

The decay schemes of the two isotopes in question are in complete in the
database, hence the problem. A modofication to the code has been introduced in
v7.0 for all isotope without a valid decay scheme will be treated as stable.
