Abstract : The root mean square angle technique reported earlier (NYO-635) is extended to the calculation of buildup factors in iron, tungsten, lead, and uranium for 1,..., 8 Mev photons and a pure Compton scatterer for 1, 2.5, and 10 mc2 photons. Computations are carried out to 20 mean free paths for the metals and 40 mean free paths for the Compton scatterer. The behavior of the buildup factors as functions of the initial energy for the heavy elements is found to differ qualitatively from that for iron and the pure Compton scatterer.
