dear all
I have simulated spallation reaction of thick Hg target with various proton
energi in range 100 MeV - 1000 MeV.
I want to know about the neutron yield.
what i get from file_name00x.out was :
neutron yield for 100 MeV proton is 1.1xx E+01, 1.2xxE+01 for 200 MeV.
Adonai said: It's obviously wrong.
here the file is :
