Question
A beam of mesons contaminated with μ+ mesons is passed through an
iron absorber. Given that the interaction cross-section of л mesons with
iron is 600 mb/nucleus, calculate the thickness of iron necessary to attenuate
the beam by a factor of 500. Explain why muons will be reduced to a
much less extent. (The density of iron is 7,900 kg m-2, the atomic mass being
55.85 amu)
