Class Information
Number: 250/251
Name: Radiant energy > Electrically neutral molecular or atomic beam devices and methods
Description: Subject matter comprising means for producing or utilizing a unidirectional stream of molecules or atoms having no net electrical charge, usually through a vacuum with thermal velocity and methods using such means. Such devices and methods may include magnetic field means to deflect, divert or select a portion of the beam of a desired energy level and may also provide means for subjecting the selected portion of the beam to a microwave electromagnetic field to excite the molecules or atoms of the beam at a resonant frequency, causing a transition of the energy state of the molecules or atoms from one energy-level to another.
