Question

The Compton scattering of a gamma-ray from an essentially free electron is depicted by the following. The relationship between theta and phi is given as phi = cos [(1 + alpha)tan theta/2]. Show that the recoiled electron is never scattered backward. Write the physical interpretation of the following mathematical expressions: i) mu_a(E)I (E) dE ii) integral_all E mu_a (E)/rho I(E)dE A narrow beam containing 10^20 photons having an energy of 6 MeV impinges perpendicularly on a layer of lead 12m thick, having a density of 1.34 g/cm^3. How many interactions of each type (PE, PP, and Compton) occur in the lead?

Explanation / Answer

recoiling has the value of teta to be 180. as tan 180 is not defined and hence there will be no recoil
