Two monoenergetic neutron beams moving with 3x10 cm/sec. The number densities of these beams are n =2x10 #/ cm and n, =4x10 #/ cm and these two beams intersect at an angle of 60. Please set the direction of the beam 1 as the x-axis for calculating the current vector. Answer the following questions : 1) Please calculate the neutron flux and current in the region where they intersect. 2) Calculate the net current through a surface perpendicular to the beam 1. I, 60% I, 3) Represent the angular currents for the beam 1 and beam 2 in terms of , and ,.
