摘要：

The degeneracy of the yellow 1S orthoexcitons in Cu2O is lifted by wave vector dependent electron-hole exchange. This interaction scales quadratically with k and strongly depends on the direction of the wave vector. Therefore it is interpreted as an anisotropic correction of the effective exciton mass. This can explain the discrepancies in the measurements of the exciton mass in Cu2O reported so far. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
