A high-energy beam of neutrons of intensity 10 6 /s traverses a target of 238 U in
Question:
A high-energy beam of neutrons of intensity 106 /s traverses a target of 238U in the form of a thin foil whose density per unit area is 10−1 kg/m2. If the elastic and inelastic cross-sections are 1.4b and 2.0b, respectively, calculate:
(a) The attenuation of the beam;
(b) The 4 The delta function is defined by the condition
where α is a real constant, implying δ(x – α) = 0 if x ≠ a, and
It is discussed in, for example, Section 13.3.2 of Martin and Shaw (2015), where derivations of its important properties, including (B.48), may be found. Rate of inelastic reactions; and (c) the flux of elastically scattered neutrons 5 m from the target, averaged over all scattering angles. (In practice the neutrons are emitted at small angles relative to the beam direction.)
Step by Step Answer:
a If the incident and final fluxes are J i and J f respectively then after traversing a thickness ...View the full answer
