摘要：

We investigate the fine structure of the heavy hole exciton in high quality GaAs-GaAlAs quantum wells, by magneto-optics in high fields. The fourfold degeneracy of the heavy hole exciton ground state is lifted completely in the field and all four components are observed. The field dependence supports the exchange interaction as the leading mechanism for the B = 0 splitting. © 1990.
