摘要：

The excitonic reflectivity spectra and the wavelength derivative reflection spectra have been investigated. The n = 1, n = 2 and n = 3 states of the A, B and C exciton series are determined. The exciton binding energies and exact values of the band gaps of all three intervals Gamma(7)(V1)-Gamma(6)(C1), Gamma(6)(V2)-Gamma(6)(C1) and Gamma(7)(V3)-Gamma(6)(C1) have been calculated. Data on the splitting due to the crystal-field and the spin-orbit interaction are determined as well.
