Abstract
The order-dependent valence-band splitting and direct-gap reduction in spontaneously ordered indirect-gap AlIn are determined by dark-field spectroscopy at room temperature. Similar to direct-gap GaIn both parameters depend on the degree of long-range -type order. We obtain the direct gap for disordered and the order-induced changes of the spin-orbit splitting and the crystal-field splitting normalized to the direct-gap change for perfectly ordered AlIn.
