Abstract
We discuss our previous results in the perspective of recent developments. We argue that intervalley kinetic and overlap terms are artifacts of a different incorrect formalism, and we thus maintain our prediction of deep interstitial and substitutional single donors and core excitons in Si. We outline an experiment in which the intervalley effect, the core-hole-electron interaction, and the shallow-deep instability may all be directly observable in Si.Keywords
