A narrow beam of thermal neutrons passes through a plate of iron whose absorption and scattering effective

Question:

A narrow beam of thermal neutrons passes through a plate of iron whose absorption and scattering effective cross-sections are equal to σa, = 2.5 b and σ8 =11 b respectively. Find the fraction of neutrons quitting the beam due to scattering if the thickness of the plate is d = 0.50 cm.
