Observation of the 2p exp 4 ( exp 1 S)ns,md excitations in atomic fluorine

In the first observation of the autoionizing resonances converging to the 2p exp 4 ( exp 1 S) series limit of atomic fluorine the decay of the resonance states into the ( exp 1 D) epsilon l; partial channel has been measured by photoelectron spectrometry with the use of synchrotron radiation. We present the initial results of this work. Copyright (c) 1996 Elsevier Science B.V. All rights reserved.
