Abstract
For the first time there is experimental evidence for a distinct fine structure in the exciton spectrum of cubic semiconductors caused by envelope-hole coupling. As an example, we present measurements of the exciton in cubic ZnSe by two-photon absorption. The highly resolved threefold energy splitting into , , and states is explained within a spherical model. We determine the spherical effective-mass parameter and give an upper limit for the cubic parameter .
