We propose a simple alternative to the sphericity as a measure of jet structure in e/sup +/e/sup -/ annihilation. Our variable has the property that it can be reliably calculated in pertubation theory in quantum chromodynamics (QCD) for large Q/sup 2/. It is not sensitive to the details of quark and gluon decay into color-singlet hadrons. We discuss the nonperturbative effects which are important at moderate Q/sup 2/.
