Re: residual nuclei before/inside/after water target AND bragg curve]

Dear Ercan,

1) If I'm not mistaken the water target and the usrbin both start
 at z=10cm, therefore a bragg peak at z=37 cm means that its depth in
water is 37-10=27 cm (approx..)
2) +3) +4 )you can use the USRBDX or the USRYIELD estimators. Both can
score particle current or fluence on a boundary. Tey are both
double-differential estimators, therefore you can also get the fragnents
angular distribution and spectra.
Be careful with normalizations!
Since the "heavyion" particle includes all ion species, you can select the
isotope that you wish to score with the AUXCARD command.
You can have a look at the "scoring" lecture from the last fluka course
( www.fluka.org --> courses-->athens-->program ) to have details, and of
course to the manual.
 Hope this helps
Paola
