“…Being site and state selective [18][19][20][21][22][23][24][25][26], dispersed fluorescence provides extensive information on the emitter and on the initial and final states of the emission process. These advantages are routinely utilized in, e.g., astrophysics to characterize emission lines in small system [37].…”

“…The nozzle was cooled by a liquid He flow and the temperature was stabilized to ±0.5 K. The degree of condensation, i.e., the ratio of monomers to clusters, was about 50%. The mean cluster size of N 20 = was chosen large enough to enable detectable photon rates with the present advanced single-photon counting technique PIFS [18]. It was controlled following the formula of [27] with the present stagnation pressure of 518 mbar and nozzle temperature of 60 K.…”

“…Measurements of emitted photons provide information about the emitter (site selectivity), its transition initial and final states (state selectivity), and on the lifetime of the emission process (time resolution). The photon-induced fluorescence spectroscopy [18] (PIFS) has been successfully used for the quantitative investigation of photoionization, Auger-, and autoionization processes in molecules [19][20][21][22][23][24][25][26] with particular sensitivity to processes with low-energy electron emission [19][20][21]. Despite the advantages mentioned above, fluorescence subsequent to ICD processes has not yet been recorded, as the target density in the necessary cluster experiments was very low.…”

Detecting ultrafast interatomic electronic processes in media by fluorescence

Interatomic coulombic decay (ICD), a radiationless transition in weakly bonded systems, such as solutes or van der Waals bound aggregates, is an effective source for electrons of low kinetic energy. So far, the ICD processes could only be probed in ultra-high vacuum by using electron and/or ion spectroscopy. Here we show that resonant ICD processes can also be detected by measuring the subsequently emitted characteristic fluorescence radiation, which makes their study in dense media possible.

“…The UV/visible and VUV photons released in the second and third steps of the cascade (Fig. 1c) were simultaneously detected by the well-established set-up for photon-induced fluorescence-spectroscopy [20] (PIFS). It has already been successfully utilized to investigate autoionization [21,22,23,24,25] and Auger decay [26,27,28,29,30] in molecules.…”

Fluorescence cascades evoked by resonant interatomic Coulombic decay of inner-valence excited neon clusters

et al. 2017

View full text Add to dashboard Cite

Resonant interatomic Coulombic decay (RICD) in inner-valence excited neon clusters is observed by a combination of vacuumultraviolet (VUV) and UV/visible fluorescence spectroscopy. These ultrafast interatomic electronic processes efficiently quench radiation emission from inner-valence excited clusters. After RICD took place, outer-valence excited clusters relax further by emission of fluorescence. The direct correspondence of the structures observed in the VUV and UV/visible fluorescence signals implies that the final states of the spectator RICD decay by a cascade of radiative decays: First, by the Rydberg-to-Rydberg transitions in the UV/visible spectral range, and then, by the Rydberg-to-valence transition in the VUV range. Our study demonstrates a possibility of detecting interatomic electronic processes by UV/visible fluorescence spectroscopy.

“…The experiment was carried out at the undulator beam line UE56/2-PGM2 of BESSY II, Berlin, using photon-induced fluorescence spectroscopy [21,22]. The energy of the exciting synchrotron radiation was varied in steps of 5 meV covering the energy range from resonance R2 to R4 whose energies are 92.425 and 92.560 eV, respectively [17].…”

The energy dependencies of alignment parameters A20 for KrII 4p(4)5p states after the Auger decay of the KrI 3d(9)np resonances were investigated theoretically and experimentally for the first time in the Raman regime with the bandwidth of the exciting radiation (deltaE(FWHM)=20 meV) smaller than the natural width of the resonances (Gamma approximately 80 meV). The observed energy dependence is due to the in-terference between the different resonance channels and the direct photoionization channel. A strong energy dependence for both the orientation parameter O10 and the photoelectron angular distribution parameter beta(el) is also predicted.
