Angle-resolved photoelectron spectroscopy of the DABCO molecule probed with VUV radiation

Audrey Scognamiglio, Lou Barreau, Constant A. Schouder, D. Cubaynes et autres

We report a study of the diazabicyclo[2.2.2]octane (DABCO) molecule photoionized using VUV synchrotron radiation in combination with an ion--electron coincidence spectrometer. We determine accurately the adiabatic ionization energy to $7.199\pm0.006$~eV. Two vibrational progressions of DABCO cation ground state are resolved at $847~\text{cm}^{-1}\pm27~\text{cm}^{-1}$ …

L-Shell Photon Excitation Cross Sections for the Chlorine Isonuclear Sequence Clq+ (q=1−4): An Experimental Study

Jean-Paul Mosnier, Eugene T. Kennedy, D. Cubaynes, Ségolène Guilbaud et autres

We report experimental measurements of the absolute photoionization cross sections for chlorine ions in different stages of ionization, over photon energy ranges corresponding to the L-shell (2s and 2p subshells) excitations. Single, double and triple photoionization channels were investigated for the ions …

Neutralization of Multiply Charged Ground-State Ions by Collective Electron Transfer from an Environment

Catmarna Küstner‐Wetekam, Nils Kiefer, Johannes H. Viehmann, Niklas Golchert et autres

Highly charged cations are omnipresent species after the interaction of high-energy or high-intensity light with matter. When embedded in environments, the mechanism and outcome of the redistribution of the cation's charge are crucial for the further fate of the whole system. Generally, …

Photoionization Study of the 4s24p4(3P1)nd, 4s24p4(1D2)nd and 4s24p4(1S0)nd Rydberg Series of Rb2+ via the Modified Atomic Orbital Theory

Oumar Baba Dia, Malick Sow, Moustapha Kebe, Papa Ndiaye et autres

We consider the 4s24p4(3P1)nd, 4s24p4(1D2)nd and 4s24p4(1S0)nd Rydberg series of Rb2+ originating from the 4s24p5(2P01/2) ground state and 4s24p5(2P03/2) metastable state of Rb2+ converging respectively to the 4s24p4(3P1), 4s24p4(1D2) and 4s24p4(1S0) series limit in Rb3+. The semi-empirical procedure of Modified Atomic Orbital …

Auger photoelectron coincidence spectroscopy of molecules adsorbed on a gold wire surface

J. Palaudoux, P. Lablanquie, Rabah Benbalagh, Iyas Ismail et autres

Abstract In this paper, we present the results on Auger/photoelectron coincidence spectroscopy (APECS) of molecules—propanethiol and bovine serum albumin (BSA)-deposited on a gold wire surface, using a magnetic bottle electron time-of-flight spectrometer. Although this study is preliminary and conducted under low vacuum …

Multielectron coincidence spectroscopy of the Ar2+(2p−2) double-core-hole decay

Maximilian Mailhiot, K. Jänkälä, Marko Huttula, Minna Patanen et autres

The dominant decay pathways of argon $2{p}^{\ensuremath{-}2}$ double-core-hole states have been investigated using synchrotron radiation and a magnetic-bottle-type spectrometer coupled with an ion time-of-flight spectrometer. This experiment allows for efficient multi-electron-ion coincidence measurements, and thus for following the Auger cascade step by …
