In this work we have studied the 4d photoexcitation of atomic cesium vapor at high resolution in the energy range 75-90 eV. Belowthreshold, the two series of the 4d106s->4d96s6p 3,1P discrete transitions are observed to dominate the measured ion-yield spectra. The high photon energy resolution allowed us to selectively excite specific resonances. In this way the decay of the different excited states lying close to each other could be followed with a minimum of interference from overlapping transitions. Here we present the resonant Auger spectra recorded at the lowest energy 4d excited states and a preliminary analysis based on previous experimental and theoretical results.

Abstract
In this work we have studied the 4d photoexcitation of atomic cesium vapor at high resolution in the energy range 75-90 eV. Belowthreshold, the two series of the 4d106s->4d96s6p 3,1P discrete transitions are observed to dominate the measured ion-yield spectra. The high photon energy resolution allowed us to selectively excite specific resonances. In this way the decay of the different excited states lying close to each other could be followed with a minimum of interference from overlapping transitions. Here we present the resonant Auger spectra recorded at the lowest energy 4d excited states and a preliminary analysis based on previous experimental and theoretical results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
