## Abstract The binding of two free excitons into a biβexciton due to direct excitonβexciton interaction is studied. The process of biβexciton formation via excitonβphonon interaction is not taken into account. By group theory methods the wave functions of two interacting excitons are constructed f
## Abstract The excitons in semiconductors with arbitrarily complex band structure are investigated within the framework of the effective mass approximation. The influence of homogeneous external fields on excitons is studied. The formulas for the coefficient of oneβphoton and twoβphoton absorption
