The stark shift of the hyperfine structure of an atom with a2 S 1/2 ground state

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The energy levels of an atom in a2 S 1/2 ground state are examined in the presence of an electric field. It is found that the hyperfine structure of the ground state is Stark shifted. This Stark shift is estimated in a crude fashion. This estimate is in reasonahle agreement with the experimental result in the case of133Cs where the Stark shift of the hyperfine structure has been measured. Theg factor of the ground state is not influenced by an electric field.

Riassunto

Si esaminano i livelli di energia di un atomo nello stato fondamentale2S1/2 in presenza di un campo elettrico. Si trova che la struttura iperfina dello stato fondamentale subisce uno spostamento di Stark. Si valuta in maniera grossolana questo spostamento. Questa valutazione è in buon accordo con i risultati sperimentali nel caso del133Cs, in cui lo spostamento di Stark della struttura iperfina è stato misurato. Il fattoreg dello stato fondamentale non è influenzato dal campo elettrico.
