Abstract: A Boltzmann operator is constructed representing an observable for a direct measurement of Boltzmann functions. This operator overcomes all the pathological features inherent in the Wigner function hitherto used in the quantum mechanical derivation of the Boltzmann equation. With the help of this Boltzmann operator a Boltzmann equation, with a new quantum mechanical correction to the streaming term is obtained for a dilute gas.
