microscopic cross section of water

calculate microscopic cross section for scattering of 1 eV neutrons in water. Using N for water as 0.0334*10 24 cm -3 and scattering cross sections of 20 barns for hydrogen and 3.8 barns for oxygen. Find the scatering mean free path Expert Answer Previous question Next question

The cross section per H2O molecule is 3*0.039 = 0.117 barn. Similarly for heavy water (D2O) with bD = 6.671 fm, one obtains σc(D2O) = 5.12 barn. The cross section per D2O molecule is 3*5.12 = 15.35 barn. 4. INCOHERENT SCATTERING AND DISORDER SCATTERING CROSS SECTIONS Every element in the periodic table has a spin incoherence scattering cross

cross section of each material and was compared to the known values. The microscopic cross sections were 15 determined as 8.616 barns for copper, 4.803 barns for graphite, 186.7 barns for Lucite and 63.29 barns for water and agreed with the theoretically accepted ones within an experimental error, except for the values of water and
