Dear all,
I am using QGSP_BERT_HP physics list in Geant4 simulation. When thermal neutron interacts with Boron-10. It does not produce 6 % reaction product of alpha (1.78 MeV) and lithium (1.01 MeV). Please can someone tell me why I am not getting the 6% reaction product using this physics list. How can I modify it to show that it also shows the above reaction product?
Hi Manoi!
I do a simulation project with thermalized neutrons and B10 inside neutron converter.
I use QGSP_INCLXX_HP physics list and my version of G4 is `geant4.10.00.p03`.
With this configuration I can confirm that everything is OK with B10. Look at the numbers:
Total 360406 neutrons interacted inelastically with B10(A=10,Z=5) atoms during the run. Out of them 23058 neutrons in reaction n+B10 -> Li + alpha(1.78) and 312670 neutrons in reaction n+B10 -> Li + alpha(1.47) + gamma(0.47). This gives 6.4% for your reaction of interest.
The rest of neutrons interact with B10 in reactions like these
n+B10 -> (pnn) + 2*alpha + N*gamma
n+B10 ->n+B10 + N*gamma
