Based on a measurement of high momentum [Formula Presented] production in B decays, we determine the charmless inclusive [Formula Presented] branching fraction in the lab-frame momentum interval [Formula Presented] Using [Formula Presented] pairs collected at the [Formula Presented] center-of-mass energy with the CLEO II and II.V detector configurations, we find [Formula Presented] in the [Formula Presented] momentum range, where the uncertainties are statistical, systematic, and from subtraction of background from B decays to charm, respectively.
