Abstract
A perturbation Brillouin-Wigner approach to anisotropic exciton problem, ba sed on a hyperspherical formalism, is developed. The binding energies and o scillator strengths of elongated as well as flattened excitons are calculat ed numerically. It is shown that with an increase of the anisotropy degree the oscillator strengths are markedly redistributing between optically acti ve active.
