摘要：

The theoretical line shape of the two-dimensional indirect exciton is derived. The photon-energy dependence of the absorption coefficient is characterized by the step function, in contrast with the square-root dependence for an ideal three-dimensional one. The complete agreement between theory and experiment is mentioned on the indirect-band edge of β-GaSe at 4.2 °K with the inclusion of the relaxation effects. © 1969 Società Italiana di Fisica.
