Hi Nicholas,

Well I know a software that can be used to make it called MGGPOD (http://www.mpe.mpg.de/MEGA/mggpod.html). I tried to install this package in linux, but I could not. I want to simulate an instrument for astronomical applications, observations in X and Gamma ray.

So, if it is not possible, to simulate delayed emission in GEANT4, the better solution is to use Cosima..

Manuel
