Abstract: | The transfer of magnetic polarization between the levels2 P 1/2 and2 P 3/2 in sensitizing collisions of excited sodium atoms and noble-gas atoms has been studied. Deviating from a previous study on this topic the nuclear spin was now decoupled by means of a strong magnetic field. As a result moreD 2σ?-quanta could be detected in the sensitized fluorescence following an excitation withD 1σ+-light. From the measurement of the fluorescence intensitiesI D1σ± andI D2σ±, cross-sections peculiar to polarization transfer could be derived. In the case of He and Ne these cross-sections together with the cross-sections of normal sensitizing collisions could be traced back to Grawert's parametera 1 anda 2 hence confirming the assumption of the spin being “at rest” during the collision. |
