I tried Geant4.9.2 (last version) by simulating thermalized neutrons on BF3 tubes filled with 1 bar of BF3.
I have 2 peaks of full energy deposited. One peak is at 2273 keV, the other one at 2750 keV. Normally I should get one peak at 2310 keV and the other one at 2790 keV. So, for both peaks , I get an under estimation of 40 keV. The branching ratio is correct.
I used LHEP_PRECO_HP for slow neutron interaction.
Isn't there a mistake in the Q value of the reaction, or anything similar ??? I have just realized that the total deposited energy is also wrong for 3He+n : I get 1271 keV instead of 764 keV ! The last result with 3He worked fine with previous GEANT4 version...
Could anybody check the total energy deposited for these 2 reactions ? Thanks,
