Hi Andrzej,
if you want for example to study a given reaction in a particular region
of interest, I would suggest you to do an event analysis by using:
- the MGDRAW user routine (activated by the USERDUMP card) for
the general analysis of each transport particle;
- the STUPRF and STUPRE user routines, where (in the cases of
hadrons/muons and electrons/photons respectively) you can get
informations about the occurred interaction and the secondaries, that
have been produced.
If for example you want to count the interactions of interest in the whole
target, you can work in the USDRAW subroutine (in mgdraw.f);
if you are interested only at the secondaries that come out from your
target, you can work in the BXDRAW (boundary crossing drawing) subroutine
(always in mgdraw.f).
In this second case, if you are also interested to the calculation of
the total interaction rate (i.e. the total cross section, without
selecting a particular reaction) I would suggest also to consider the
USRYIELD card, that - with an appropriate setting of what(6) - allows
the calculation of the plain double differential cross-section or the
invariant cross-section (the warning is: the calculation has a little
meaning in the case of thick target)
Hope it helps,
cheers,
Anna
