Dear Masithoh,

The problem with your input is the BEAM card. You are defining a proton 
beam with energy 100MeV but with momentum spread WHAT(2) Dp(FWHM)=2.355 
GeV! Change the Dp to 0 and you will a value close to Herrera et al paper.

dear FLUKA users

I have simulated spallation reaction of thick Hg target with various proton
energi in range 100 MeV - 1000 MeV. Some of them (100 MeV - 300 MeV)are
attached. 
I want to know about the neutron yield.
I read at "Accelerator Driven System Design FLUKA Exercise, ICTP Lecture" by
Herrera Martinez and Yacine Kadi that it can be extracted from
file_name00x.out
But what i get from the file is :
neutron yield for 100 MeV proton is 1.1xx E+01, 1.2xxE+01 for 200 MeV. (Too
much higher isn't it?)
And I get 2.9xx E+01 for 1000 MeV proton. (i think it's approach Herrera&Kadi
result in their paper).
Can you tell me what i did wrong?
Any respons will be greatly appreciated.
Thank you
