Reports spin-unrestricted self-consistent LMTO Green-function calculations of the electronic and magnetic structure of 3d and 4d transition-metal impurities in crystalline silicon. Both defects sites of tetrahedral symmetry are considered. The early interstitial and late future experimental studies. In the case of 4d impurities the e and t2 states are more delocalized and, as a consequence, the e-t2 splitting is found to be even larger than that of the 3d ions. Therefore all 4d ions in silicon are predicted to have low-spin ground states.
