Atomic and molecular beams are widely used nowadays in physics and chemistry experiments. The nozzle, or free-jet, molecular beam is a neutral beam extracted from an under-expanded, supersonic, continuum jet expansion from a high-pressure gas source into a low-pressure ambient background. The beam has many special properties which are exactly demanded in atom/molecular experiments.By properly analyzing the formation mechanism of supersonic gas jet, the factors directly related to transverse momentum Atomic and molecular beams are widely used nowadays in physics and chemistry experiments.
