Consider two uniform neutron beams moving with 3x107 cm/sec given in the figure below. The number densities of neutrons for the beam 1 and 2 are 2x106 #/cm3 and 4x106 #/cm3, respectively. Please set the beam 1 direction as x-axis and assume that the beam 2 is on the plane formed by x- and y- axis. Please answer the following questions (10 pt) : (a) Calculate the intensities of the beams each. (b) Calculate the scalar flux and the net current at their interaction point with respect to a surface having its outer normal vector of ,. I, %3D
