A beam having a flux of 10^10 particles per second per cm^2 is incident on a target. The differential cross section is d(sigma)/d(omega) = (b^2)(sin(theta))^2. What is the total cross section? What is the value of b if the total number of scattered particles into 4*pi steradians is 10^8 particles per second? How is your answer affected if the beam flux is 10^16 particles per second per cm^2 and the total scatter rate is 10^8 particles/sec?
