Abstract

Using data collected with the CLEO II detector, we have observed the isospin-violating decay

D_{s}^{* +} \to D_{s}^{+} π^{0}

. The decay rate for this mode, relative to the dominant radiative decay, is found to be

γ (D_{s}^{* +} \to D_{s}^{+} π^{0}) / γ (D_{s}^{* +} \to D_{s}^{+} γ) {= 0.062}_{- 0.018}^{+ 0.020} \pm 0.022

.
