Hi Alberto,
I tried to do it using the USRYIELD estimator. These are the corresponding
lines from my input file:
USRYIELD 1413.0 201.0 21.0 R_TARGET R_VAC 1.0 etotal
USRYIELD 20.0 0.0 1.0 3.1415926 0.0 3.0 &
The kinetic energy of the projectile is 10 GeV, but I put the upper limit
for energy to 20 GeV purposely in order not to loose some "overenergetic"
particles.
I am not completely sure if these lines are correct, but the resulting
number I have got for a single event is 0.64856.
Am I right that one have to multiply this number by the width of the angular
interval and by the width of the energy interval? This gives 0.64856 * PI *
20 = 40.7502 GeV of total energy which is ~4 times greater than the energy
of the projectile.
Where am I wrong?
The source code and the input file with the USRYIELD cards can be found
