ABSTRACT The molecular beam tube apparatus includes a source for providing a directed beam of molecular particles a first state selector for selecting a portion of the particles in the beam, a radio frequency transition section downstream from the first state selector for causing resonance transitions of some of the selected beam particles means for producing a weak generally homogeneous magnetic field in the radio frequency transition section, a second state selector downstream from the radio frequency transition section for selecting a further portion of the beam comprising those beam particles that have undergone a resonance transition and detecting means responsive to said particles in the further portion of the beam, including a mass spectrometer. The improved apparatus provides a pair of generally horseshoe shaped permanent magnets oriented to provide two gaps spaced about 180° apart, a first gap being downstream of a radio frequency transition section in the path of the beam, and a second said gap being downstream of the first. A first pole piece assembly is within the first gap and driven by permanent magnets, and a second pole piece assembly is within the second gap and driven by the permanent magnets, whereby the first pole piece assembly provides the second state selector, and the second pole piece assembly provides the mass spectrometer in the detecting means, the magnetic circuits of said second state selector and said mass spectrometer being in series.
