The patent describes a molecular beam source for a molecular beam tube frequency standard using a barium oxide molecule of the form Ba138O16 having spinless atoms and using electrostatic state selection, which source includes a thin-walled refractory electrically conductive oven tube containing Ba138O916. The oven tube, which is chemically inert to barium oxide, is surrounded by a thermionic electron emitter which is made negative with respect to the oven tube. Electrons emitted from the electron emitter bombard the oven tube and heat the barium oxide to a temperature at which Ba138O16 molecules are evaporated. Modified author abstract
