Hyperfine structure hydrogen

Web23 jun. 2024 · Article information Abstract An intense source of cold hydrogen atoms in a supersonic beam is presented. H and D atoms are produced from pure samples of H 2 and D 2 using a barrier discharge near the orifice of a cryogenic pulsed valve. WebHyperfine Structure The proton in a hydrogen atom is a spin one-half charged particle, and therefore possesses a spin magnetic moment. By analogy with Equation ( 5.44 ), we can write (7.141) where is the proton magnetic moment, the proton spin, the proton mass, and the proton -factor.

Precise Measurement of Hyperfine Structure of Cesium 7

WebWe start with a Galilei-invariant symplectic model of two charged particles with spin and magnetic moment in interaction, which could serve as a model for the (classical) hydrogen atom. To this model we apply two different versions of geometric quantization and we obtain a hamiltonian operator which is (apart from some numerical constants) the well-known … WebFigure 7 shows a revised version of the structure of the hydrogen atom, including the Lamb shift and hyperfine structure.
