Abstract
The Boltzman equation, for energy deposited by fast electrons in the presence of an applied magnetic field, is solved in the diffuse beam approximation. The solution is obtained by a simple coordinate transformation which is valid both when λ/rL⩽0.25 (λ = mean free path, rL = Larmor radius) and when λ/rL ⩾4.5. The half‐space solution is used to determine the dose in a gas. The theoretical results are compared with experiments. It is found that agreement is better than *10% for cases of interest.Keywords
