Precision Measurements of Forbidden Transition Frequencies Using Stimulated Raman Scattering

The possibility of precision measurements of frequencies of forbidden transitions of cold atoms in a trap using stimulated Raman scattering is shown. Transition 1 S –2 S in a hydrogen atom, in which the atom passes from level 1 S to level 2 S via intermediate level 3 P is considered in detail. In th...

Description
Summary:The possibility of precision measurements of frequencies of forbidden transitions of cold atoms in a trap using stimulated Raman scattering is shown. Transition 1 S –2 S in a hydrogen atom, in which the atom passes from level 1 S to level 2 S via intermediate level 3 P is considered in detail. In this case, the frequency of the pump field (103 nm) is close to the frequency of the 3 P –1 S transition, while the stimulated scattering frequency (656 nm) is close to the frequency of the 3 P –2 S transition.
