atomic beam

An atom beam, also known as an atomic beam, is a stream of molecular rays composed of monatomic molecules from a vaporized metal. These beams consist of atoms or molecules moving in the same general direction, typically within a vacuum chamber. The low density of molecules in these beams allows them to move independently, making their properties easier to study through experiments involving deflection in electric and magnetic fields or by directing the beam onto a target. This technique is valuable for understanding molecular structure, properties, and interactions.12
