The electron-core-hole interaction is studied via energy derivative reflectance spectra of 20-eV transitions from Ga 3dcore levels to lower conduction-band final states in GaAs1−xPx alloys. A two-level anticrossing behavior of line shapes and threshold energies as the relative positions of the L and X minima invert yields a previously unanticipated L−Xmixing energy |VLX|∼50 meV.
