(10.6) The typical energy of a neutrino in the Cosmic Neutrino Background as ported out in Chapter 5, is E,, ~ kT,, ~ 5 × 10-4 eV. What is the approximate interaction cross-section ơw for one of these cos- mic neutrinos? Suppose you had a large lump of 56Fe (with density p 7900 kg m. What is the number density of protons, neutrons, and electrons within the lump of iron? How far, on average, would a cosmic neutrino travel through the iron before interacting with a proton, neutron, or electron? (Assume that the cross-section for n teraction is simply συ, regardless of the type of particle the neutrino interacts with.)
