The Gas Phase Photoemission (GAPH) beamline is the only one at Elettra specifically devoted to research on gaseous systems. |
Gas Phase highlights | Publications![]() "Position” does matter: The photofragmentation of the nitroimidazole isomers
Experimental and theoretical spectroscopic methods have been combined to disentangle the fundamental mechanism of VUV induced fragmentation of the three isomers of nitroimidazole. P. Bolognesi et al. J. Chem. Phys., (2016)
![]() Enhanced Ionization of Embedded Clusters by Electron-Transfer-Mediated Decay in Helium Nanodroplets We report the observation of electron-transfer-mediated decay (ETMD) involving magnesium (Mg) clusters embedded in helium (He) nanodroplets.. A. C. LaForge et al.; PRL 116, 203001 (2016) ![]() Negative-Ion/Positive-Ion Coincidence Yields of Core-Excited WaterThe analysis of negative-ion/positive-ion (NIPICO) and negative-ion/positive-ion/positive-ion coincidence (NIPIPICO) events provides new information on pathways leading to negative ion production in water. ![]() Fragmentation of Small Molecules after Core Excitation and Core Ionization Studied by Negative-Ion/Positive-Ion Coincidence Experiments

Proposal SumissionWe invite users and collaborators to discuss their proposals with the beamline local contacts well in advance before the submission deadline. This is crucial for a careful assesment of the experiment feasibility and may lead to improvements in the proposed experimental plan. Our website provides a wealth of informaiton on experiment feasibilty and proposal submission. For more info, please vist the user info section. |
Call for proposalsNext deadline for proposal submission at link: Elettra_DL and : CERIC_DLAll proposals requiring use of the laser will be performed at the branch line. |
