GAS PHASE PHOTOEMISSION and its users

The Gas Phase Photoemission (GAPH) beamline was born as a joint venture between the Istituto Nazionale di Fisica della Materia (INFM), the Consiglio Nazionale delle Ricerche (CNR) and the Sincrotrone Trieste scpA (ST), and at present it is operated by a Research Team (ST+CNR).

It is the only beamline at ELETTRA specifically devoted to research on gaseous systems.
The beam line has been operational since the end of 1997. In the first 10 years, about 140 beamtimes have been awarded by the international panel and successfully completed, out of the almost 230 submitted proposals.About 146 papers have been published in the sdame period in JCR journals, with an average impact factor about 2.9.
Around 40% of the experiments are performed by foreing groups.
Due to the large variety of the experimetal techniques available at GAPH, that can also request for different experimental chambers, first time users are strongly encouraged to take contact with scientists of the staff before submitting a proposal.

RESEARCH FIELDS

The active in-house and users' research program at GAPH covers, among the rest, the following areas of activity

• studies of electron correlation in atoms and molecules in double photoionization and inner shell ionization and decay;

• high resolution studies of electronic structure and dynamics of atoms and molecules (with core level photoabsorption, photoemission and dispersed fluorescence);

• characterization of reactive gases, radicals, transient species (electron and ion coincidence spectroscopies);

• studies of complex molecules (biological and other organic molecules, and organometallic complexes)

• studies of inorganic and organic clusters
