Summary
By a study to determine the preferential absorption of one component of circularly polarized light in a molecular magnetic dipole transition in16O2 we have determined an upper limit to the parity impurity of the states involved in the transition. We find the amplitude of the PNC part of the states are less than or equal to 3·10−8 from a measurement of the circular polarization that is less than or equal to 6·10−4.
Riassunto
Con uno studio per determinare l’assorbimento preferenziale di una componente della luce polarizzata circolarmente in una transizione molecolare di dipolo magnetico nel16O2, abbiamo stabilito un limite superiore alla impurezza della parità degli stati coinvolti nella transizione. Troviamo che le ampiezze della parte PNC degli stati sono minori od uguali a 3·10−8 in base a misure della polarizzazione circolare che è minore od uguale a 6·10−4.
