Observation of asymmetric Stark profiles from plasmas created by a picosecond KrF laser

High-resolution extreme-ultraviolet spectra from solid targets irradiated by a picosecond KrF laser focused to 10 to the 16th W /sq cm have been recorded. The line profiles of transitions in Li-like fluorine and oxygen are asymmetric and up to 2 A in width. Calculations indicate the presence of tran...

Zusammenfassung:	High-resolution extreme-ultraviolet spectra from solid targets irradiated by a picosecond KrF laser focused to 10 to the 16th W /sq cm have been recorded. The line profiles of transitions in Li-like fluorine and oxygen are asymmetric and up to 2 A in width. Calculations indicate the presence of transitions of the type 2p-3p and other forbidden Stark components. (Author)
