So I am looking to shoot a set of neutrons , all at 2 millielectronvolts so it is very low energy. I am trying to use various physics models in order to properly simulate the scattering and elastic reactions and inelastic reactions and am measuring the total number of times that the hadElastic process (as recorded in SteppingAction under GetProcessName() == "hadElastic" , and also the particle is always a Neutron so the condition is that GetParticleName() == "neutron" and the process is hadElastic ) occurs for the following processes : QGSP_BERT_HP, QGSP_BERT_EMV, QGSP_BIC_HP and FTFP_BERT. For QGSP_BERT_HP the hadElastic process for neutrons occurs 1959 times, for QGSP_BIC_HP it occurs 1959 times and for QGSP_BERT_EMV it occurs 661 times and even fewer times for FTFP_BERT.
Now I know that the slight differences between the BERT and BIC are simply due to slight differences in the estimate of scattering processes of the Bertini vs the Binary Cascade model. However I wanted to try to ensure that I have a thorough understanding of the types of elastic scattering and neutron capture that are simulated by the HP process versus the EMV. I know that HP is High Precision Neutron Model and the EMV is a variation of the standard EM package. So for Neutron scattering off a group of Aluminum atoms, what kind of processes would be recorded in the EMV vs HP model ? I know there is coherent elastic scattering in both cases but what are the kinds of scattering that geant4 would record for hadElastic in QGSP_BERT_HP vs for QGSP_BERT_EMV ?
Thank you for any help you may have.
