Data Analysis of Molecular Dications Fragmentation Processes by Double Photoionization with Synchrotron Radiation

In this paper is presented a summarizing description of the collection and computational analysis of the relevant data recorded following a double photoionization experiment on molecular species of interest in astrochemistry. In particular, the computational procedure used to analyze experimental data collected in the double photoionization of allene molecules by tunable radiation in the 25.0–45.0 photon energy range of the GASPHASE and CiPo beamlines of the ELETTRA synchrotron facility of Basovizza (Trieste, Italy) is outlined and discussed. Data presented are recorded using the ARPES (Angle Resolved PhotoEmission Spectroscopy) end station, which is a molecular beam apparatus coupled with a PEPIPICO (Photoelectron-Photoion-Photoion Coincidence) technique and TOF (Time-of-Flight) mass spectrometry, in three different beamtimes.
