NUCLEAR PHYSICS. CROSS SECTION (Probably Mott cross section). Please be clear.
Deuterons with an energy Ekin = 5 MeV are perpendicularly incident on a tritium target, which has a mass occupancy density μt = 0.2 mg/cm2, to investigate the reaction 3H(d,n)4He.
a) How many neutrons per second pass through a detector with a receiving area of A = 0.002 m2 which is at a distance R = 3m from the target and an angle θ = 30◦ to the direction of the deuteron beam, considering a differential cross section dσ/dΩ at this angle is 13 mb/sr and the deuteron current applied to the target is Id = 2 μA?
b) How many neutrons per second does the detector receive if the target is tilted so that the same deuteron current now approaches 80◦ instead of 90◦?
