Hello,

I am simulation the response of different detectors to radioactive material. Therfore I am using /gps/particle ion e.g. /gps/ion 27 60 0 0 for Co60 e.g. /gps/ion 95 239 0 0 for Pu239

The decay itsef is working great - I tried lots of differnt nuclids.

when I set /gps/energy 0 eV the given mometum direction is lost (as it should be) but the particle is moving through the world. - what should not be. It is not important for ions with decay times of some years. - Worst case I have to make more runs.

But for Pu239 with with decay time in the order of thousands years, most of the ions have left the world bevore they dacay.

Is this a bug, that the ions are not stationary? I tried to external stop the ions wiht some interactions, (in the physics List of GenericIon) but with no effort.

Thanks for any hint or suggestion.

Karen
