One-loop divergencies in the theory of gravitation

All one-loop divergencies of pure gravity and all those
\nof gravitation interacting with a scalar particle are calculated. In the case
\nof pure gravity, no physically relevant divergencies remain; they can all
\nbe absorbed in a field renormalization. In case of gravitation interacting
\nwith scalar particles, divergencies in physical quantities remain, even
\nwhen employing the socalled improved energy-momentum tensor.
