Question Helium counter - neutrons, energies of secondaries tritum and proton

Hello. 

Probably is a error in Physics List: LBE

I hava a simulation of helium3 neutron counter. 

I use:

You are using the simulation engine: LBE 5.3


In Physics List: LBE 5.3 products from reaction n+3He -> tritum+proton+764 keV
Should be:                     Is:
(~191 keV - tritum)            (~191 keV - tritum)
(~573 keV - proton).           (~427 keV - proton)  
sum: ~764 keV                  sum: ~620 keV


In other Physics list, eq.  QGSP_BIC_HP values are OK. 

I suppose, that in LBE Physics List is something wrong.
