The molecular beam source is used to produce a molecular beam consisting mainly of dimers. The beam is referred to as supersonic because its propagation in a vacuum occurs at a speed higher than the speed of sound under the same conditions. The operation principle of the source based on the rapid cooling of the injected particles associated with a significant pressure difference. Under these conditions, the rotational and oscillatory movements of the nuclei of the atoms forming the molecule are reduced so that the molecules are in lower oscillatory and rotational states. It allows for the simplification of the spectra used in laser spectroscopy. The source makes it possible to create a beam containing cadmium atoms: Cd\u2082 or cadmium noble gas (Ng) dimers CdNg.<\/p>\n

The device was reported to the Patent Office as an invention. Application number: P.419598.<\/p>\n
