The nuclear cross-section is a function of the neutron energy.[1] It determines the probability that an incoming neutron is lost, absorbed, reflected, or triggers a fission event in the nucleus of the atom.[1] different for each isotope.[1] The units for nuclear cross-section is barns.[1] Carbon, Hydrogen, and Beryllium capture more kinetic energy from the neutrons.[2] When performing monte-carlo analysis of reactors it is time consuming to perform the energy-dependent cross-sectional lookups.[3]
