Query: Weak Interaction Contributions in Light Muonic Atoms   Weak interaction contributions to hyperfine splitting and Lamb shift in light
electronic and muonic atoms are calculated. We notice that correction to
hyperfine splitting turns into zero for deuterium. Weak correction to the Lamb
shift in hydrogen is additionally suppressed in comparison with other cases by
a small factor $(1-4\sin^2\theta_W)$.
