    • The creation and decay of photon-excited Xe 4d(5/2,3/2)(-1) core-hole states has been studied in the photon energy region 70-110 eV, where photon absorption is dominated by the strong shape resonance. Unprecedented experimental quality has enabled the stu

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • The fragmentation of the water molecule upon resonant core excitation and subsequent Auger decay has been studied by electron-ion coincidence spectroscopy. A qualitative comparison between the fragmentation patterns for H2O and D2O reveals that the anti-b

  • Interference between direct and resonant channels in near-resonance photoemission in argon
  • 2001
  • Ingår i: Physical Review A. Atomic, Molecular, and Optical Physics. - 1050-2947. ; 63:3, s. 325141-325145
  • Tidskriftsartikel (refereegranskat)abstract
    • The photoelectron spectra of argon was demonstrated during resonant photoemissions. The interference effects of the photoelectron spectra of argon was monitored by following the intensity of final states through resonant and direct channels. The need for a unified one-description of the ionization through a direct and core-excitation mediated channel was described.

  • Femtosecond pump-probe photoelectron spectroscopy of predissociative Rydberg states in acetylene

  • Ingår i: Journal of Chemical Physics. - : AIP Publishing. - 0021-9606 .- 1089-7690. ; 112:18, s. 8038-8042
  • Tidskriftsartikel (refereegranskat)abstract
    • We employ a pump-probe approach to molecular photoionization to study fast dissociation of Rydberg states in acetylene. By using time-resolved photoelectron spectroscopy to study the electronic state of the resulting ions we are able to monitor the system continuously during dissociation or rearrangement. We find that the predissociative lifetime for the 3R‴ (v′2 = 1) Rydberg state is about 150 fs. We demonstrate a powerful new technique using time-correlated femtosecond harmonic generation and laser light pulses to study the time evolution of ultrafast dynamic processes in molecules.

  • Line sharpening by PCI in the Auger decay spectrum of CO
  • 1997
  • Ingår i: JOURNAL OF PHYSICS B-ATOMIC MOLECULAR AND OPTICAL PHYSICS. - : IOP PUBLISHING LTD. ; 30:23
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • The Auger decay from the C 1s(-1) core-ionized state of CO has been studied with photon energies close to and far above threshold. Close to the threshold post-collision interaction (PCI) redistributes intensity from the low kinetic energy side to the high
