Question QGSP_BERT_HP neutron cross sections 

Forum: Physics List
Date: 03 Nov, 2009
From: <dpr@ansto.gov.au>

Hi Everyone, I have simulated the response of some semiconductor detectors to two high energy quasimononergetic beam energies at 46.5 MeV and 174.35 MeV. The response of the detector to these energies does not seem consistent with the high energy elastic cross sections for 1H and 28Si presented in the ENDF JENDL/HE-2007 library.

I noticed that the data library for 1H goes up to 100 MeV (and seems to contain 3 copies of the same data) while the 28Si data goes up to 20 MeV. I was wondering if there is any way of determining what the elastic cross section was used for my energies of interest. I realise that above 19 MeV the physics list uses the Bertini Cascade model but I would like to know how to know what the elastic cross section value was as a certain energy.

Is it possible to use the tables to their upper limits if more entires are added?

Regards, Dale.
