Why is thermal neutron with energy of 0.0253eV so important?

  1. May 9, 2013 #1
    I want to know the reason why the thermal neutrons with energy of 0.0253eV is so important. As far as I know, a neutron with an energy of 0.0253 eV is used as reference to measure nuclear cross sections such as absorption, fission, scattering, etc. And I want to know the details and more information about it. Thanks in advance.
