SUMMARY

The discussion focuses on the neutron powder diffraction process at Oak Ridge National Laboratory (ORNL) and the reactions involved when mercury is bombarded with protons in the energy range of 1 to 5 GeV. The primary reaction discussed is p+Hg, which results in the emission of multiple protons and neutrons, along with the potential production of pions. The variability of the reactions is highlighted as a reason for the difficulty in finding comprehensive information on the topic.

PREREQUISITES
  • Understanding of neutron powder diffraction techniques
  • Knowledge of proton bombardment reactions
  • Familiarity with particle physics concepts, specifically pion production
  • Basic principles of nuclear reactions involving mercury
NEXT STEPS
  • Research neutron powder diffraction methods used at ORNL
  • Study the effects of proton bombardment on heavy metals like mercury
  • Explore the mechanisms of pion production in nuclear reactions
  • Investigate the theoretical frameworks for modeling nuclear reactions
USEFUL FOR

Researchers in nuclear physics, particle physicists, and anyone involved in experimental techniques related to neutron scattering and nuclear reactions.

I'm trying to understand how the neutron powder diffraction works at Oak Ridge National Lab (ORNL) and I'm wondering what the reaction is that results in neutrons being emitted from mercury after being bombarded with ~1 to 5 GeV protons. Does anyone know where I might find this information?
 
Physics news on Phys.org
p+Hg -> multiple protons and neutrons and some remaining nucleus. Pion production can happen as well. There is no fixed reaction happening.
 
That explains why I haven't been able to find sufficient information. Thank you very much.
