摘要：

The carbon-1s core exciton formation in diamond has been investigated within the framework of the local density theory associated to a molecular cluster model. By using the multiple-scattering technique to solve the one-electron Schroedinger equation it has been shown that the electron state in the exciton is rather delocalized and quite similar to a single donor state induced by a substitutional on center nitrogen impurity. Therefore a hydrogenic-effective-mass theory description of a carbon-1s core exciton in diamond is expected to be appropriate.
