Re: Re: Problem with recording particles crossing a given boundary

Hello,
sorry, I answered too quickly.
The scoring of delayed radiation is different from all the rest: radiation
products are transported once, and a factor is applied at scoring time
depending on the decay time associated to each detector. This factor
accounts for the buildup and decay of the parent nucleus at the specified
decay time. This factor is -not- available in users' routines.
Ciao
Paola
