We study the effects of atomic beams classical harmonic vibrations of micro amplitudes and low frequencies perpendicular to the wave vectors of atomic branches on the mean numbers of atoms arriving at the detectors in an atomic Mach–Zehnder interferometer, where the two atomic beams are in the same wave surface and have the same phase. We propose a vibrant factor $F$ to quantitatively describe the effects of atomic beams vibrations. It shows that: (i) the vibrant factor $F$ depends on the relative vibrant displacement and the initial phase rather than the absolute amplitude, (ii) the factor $F$ increases with the increase of the initial phase, and (iii) the frequencies can be derived from equal time interval measurements of the mean numbers of atoms arriving at the detectors. These results indicate that it is possible to detect the classical harmonic vibrations of micro amplitudes and low frequencies by measuring the variations in the mean numbers of atoms arriving at the detectors.
