WebNov 28, 2024 · The impact to the total cross section of different fission isotopes is also given there. As it follows from the comparison, calculated fission cross section underestimate the experimental data for 204 Pb(n,f) and 206 Pb(n,f) reactions. At energy of neutron about 30 MeV the agreement is satisfactory. WebThe macroscopic cross-section is an interaction rate per unit distance traveled by the neutron obtained by multiplying the microscopic cross-section (a measure of the probability of interaction expressed as an area) by the atomic density . From Section 1.5, for the data given in Table 2.3, with , the thermal macroscopic absorption cross-section ...
