RADIATIVE-CORRECTIONS TO THE DECAY TAU-]PI(K)NU(TAU) .2.

We report the results of our improved calculation of the radiative cor rections to the decay tau --> pi(K)nu(tau) which includes internal bre msstrahlung and structure dependent radiation in the radiative decay a nd point meson, hadronic structure dependent and short distance contri butions in the virtual corrections. Our result for the radiative corre ction to the ratio GAMMA(tau --> pinu(tau)(gamma))/GAMMA(pi --> munu(m u)(gamma)) is deltaR(tau/pi) = (0.16(-0.14)+0.09)%. For the ratio GAMM A(tau --> Knu(tau)(gamma))/GAMMA(K --> munu(mu)(gamma)), we obtain del ta(tau/K) = (0.90(-0.22)+0.04)%.
