Abstract. Using the multigroup discrete-ordinate form of the transport equation, the authors have studied in detail the problem of neutron wave propagation in beryllium oxide. The transfer-scattering matrix method has been employed to solve the transport equation numerically. Space and angle dependent neutron wave propagation parameters have been calculated for different frequencies of the source. Some of the calculated results are compared with earlier diffusion theory results as well as with the observed results of Ritchie and Whittleston (1972, 1973). For the first time, a reasonable agreement between the calculated space dependence of wave propagation parameters and the observed results has been obtained at all frequencies.
