Abstract :
Summary form only given. We report on the first-principle calculations for absorption spectra in Cr/sup 4+/-doped Ca/sub 2/MgSi/sub 2/O/sub 7/ crystals. The ab-initio method, which we have recently developed, is a general method to calculate electronic structure of a many-electron system.
