 Andrea, thanks a lot for quick answer.  
I have used verbose level (such as /tracking/verbose 2), as you recomend , 
but for several beamOn, because increasing size of OUT file.  
During simulation i getting all statistical results and their dispertion for
all running processes and their secondaries. U can see summary Out file: 

Like this:
Target consist of 1000  disks of  G4_Pb  material cylindrical shape
  with R(mm) = 51  Width(mm)= 0.61
  Total Length(mm)=  610
  Position of beam Z(mm) =                        0.01
 1.) Beam particle                                proton
 2.) Beam Energy(MeV)                             470

 As u can see i can get this results with including nfission 
 process and I can compare them with results in which nfission inactivate,
 but in other external application for reactor physics i want to anylise
 Kinfinity =production/absorbation.For this calculation i have to describe
 Spectrum and Total Flux and Spatial distribution of external neutron source
(so called target for Accelerator Driven System), but i have to prevent  
 double checking fission processes and other, and I know that this toolkit 
 uses ENDF multigroup library with neutron MaxE = 20MeV, that's why i have to
 stop simulations <20MeV with calling XS from  ENDF library in Geant4. It gives
 definition of external source, if i'm not mistaken) 

 Any ideas? I'll look Physics with _HP. Sorry for long output file (i see that i 
 copy Pb target results, but in fission materials idea of checking processes 
 is similar ...)

Best regards. Aleksey
