Neutron absorption cross section

Click For Summary
SUMMARY

The discussion centers on the search for reliable and up-to-date absorption cross section data for Gadolinium-157 concerning thermal neutrons. Participants highlight discrepancies in reported values, which range from 70,000 barns to 450,000 barns. A recommended resource for accurate data is the National Nuclear Data Center (NNDC), specifically their cross section database accessible at this link and further details can be found at this page.

PREREQUISITES
  • Understanding of neutron absorption cross sections
  • Familiarity with Gadolinium-157 properties
  • Knowledge of nuclear data resources like NNDC
  • Basic principles of thermal neutron interactions
NEXT STEPS
  • Research the latest data on Gadolinium-157 absorption cross sections from NNDC
  • Explore the methodology for measuring neutron absorption cross sections
  • Investigate discrepancies in neutron cross section values across different sources
  • Learn about the implications of neutron absorption in nuclear reactor design
USEFUL FOR

Researchers, nuclear physicists, and engineers involved in neutron interaction studies, particularly those focusing on Gadolinium-157 and its applications in nuclear technology.

Does anyone know anywhere where I can find reliable up-to-date cross section infromation? In particular I'm looking for the absorption cross section of Gadolinium-157 for thermal neutrons. Everywhere I look seems to give a different value ranging fro 70000barns up to 450000barns.
