[en] In this study the half-space albedo problem has been investigated for highly anisotropic scattering. For this highly anisotropic scattering the Inoenuescattering has been added to the pure-quadratic anisotropic scattering. The general solution of the one-speed neutron transport equation can be written as linear combination of the solutions which involve these scatterings. Hence, Case's eigenfunctions and the related semi-analytical methods can be used to get the albedo calculations. Some selected numerical data have been tabulated. To compare these results with the Inoeuescattering values the linear interpolation technique has been used. Successful results have been achieved. (orig.)
