Beams of Monoenergetic Neutrons

Two beams of monoenergetic neutrons with energy equal 1eV intersect at an angle of 90º. The density of neutrons in both beams is 2x10^8n/cm3. a)Calculate the intensity (current) of each beam. b)Calculate the neutron flux where the two beams intersect. c)Calculate the neutron current where the two beams intersect.

Monoenergetic Neutron Beams

Two monoenergetic neutron beams of intensities I1=2x10^10 n/cm^2/s and I2=1x10^10 n/cm^2/s intersect at an angle of 30 degrees. Calculate the neutron flux and current at the point where they intersect.

Email me for Clarification. I only need Parts C and D... I solved A and B, the answers are below. Not too much work left for 25 credits. Your help is appreciated. The only radiogenic lead isotope that is not either stable (Pb-206, 207, 208) or with a halflife of less than one day is Pb-210, which is found in nature in secular equilibrium with U-238/U-234. Suppose that we can treat a minor selenium deficiency problem by giving the patient a cocktail of polonium-210, which binds to the appropriate organ permanently. We decide to make an isotope generator which willl bind lead to it, but which releases any polonium when we pour water through it. We load the generator with Pb-210 and ... click for more
