Two beams of monoenergetic neutrons with energy equal 1eV intersect at an angle of 90 degrees. 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.

#### Solution Preview

Because, energy of neutron,

E = 1eV = 1.6*10^(-19) J = (1/2)*m*v^2

where,

m = mass of a neutron = 1.67*10^(-27) kg

v = velocity of a neutron

=> v = sqrt(2*E/m) = ...
