Dear @horvathd ,
The follow snapshot is from a generated file named “sep001.out”, you know 6Li(n,a)T, so at the column
“3.3286E-01(40.5) …TRITON” or “3.3286E-01(40.5) …4-HELIUM” ,the “3.3286E-01” is the efficiency , is it correct?
I want to get efficiency defined like I said “efficiency=the neutron react with material/the neutron incident to the sensitive volume.” because if I give particle number at “start”, not all will go into sensitive volume.
