Dear all,
thank you for previous help.
I'm interested in changing the phi (azimuthal) distribution in case
of elastic and inelastic scattering of deuteron on carbon:
D + C12 -> D + C12[*]
In STUPRF I tried to isolate this event by the following instruction:
IF ((LINEVT.OR.LELEVT).AND.(NP.EQ.1).AND.(KPART(1).EQ.-3).AND.(IJ.EQ.-3))
THEN
...
ENDIF
is it correct?
I noted that only 1 event occurs over 1'000 simulated: is it possible to
print the cross
section of these reactions?
In order to increase the statistics, is it possible to simulate only this
kind of reactions?
Since the polarization of deuteron plays a role only in the phi distribution
changing this angle does not effect the energy conservation.
So how to change it before putting the particle on the stack?
I suppose I have to change the value of
CXR(1), CYR(1) that are COMMONS in (GENSTK)
is it correct?
Best regards
Francesco Gonnella
