Abstract

International Conference on Exotic Atoms and Related Topics, EXA2021, Vienna, Austria, 13 Sep 2021 - 17 Sep 2021; The European physical journal / Web of Conferences 262, 01005 (2022). doi:10.1051/epjconf/202226201005, The strong-interaction effects both in pionic hydrogen and deuterium atoms have been re-determined with improved precision. The hadronic shift and width in pionic hydrogen together with the hadronic shift in pionic deuterium constitute a one-fold constraint for the two independent pion-nucleon scattering lengths. Furthermore, the hadronic width in pionic deuterium measures the transition strength of s-wave pions on an isoscalar nucleon-nucleon pair which is an independent quantity not related to the pion-nucleon scattering lengths. The experiment was performed at the Paul Scherrer Institute by stopping a high-intensity low-energy pion beam in gaseous targets using the cyclotron trap. The X-rays emitted by the πH and πD atoms were analysed with a high resolution Bragg spectrometer equipped with spherically bent crystals. The pion-nucleon scattering lengths and other physical quantities extracted from the atom data are in good agreement with the results obtained from pionnucleon and nucleon-nucleon scattering experiments and confirm that a consistent picture is achieved for the low-energy pion-nucleon sector with respect to the expectations of chiral perturbation theory., Published by EDP Sciences, Les Ulis

Abstract

International audience; We studied the single-photon ionization of gas-phase δ-valerolactam (piperidin-2-one) and of its dimer using vacuum-ultraviolet (VUV) synchrotron radiation coupled to a velocity map imaging electron/ion coincidence spectrometer. The slow photoelectron spectrum (SPES) of the monomer is dominated by the vibrational transitions to the equation image state. Moreover, several weaker and complex bands are observed, corresponding to the population of the vibrational bands (pure or combination) of the electronically excited states of the cation arising from their mutual vibronic interactions. For the dimer, we measure a unique large band. These spectra are assigned with the help of theoretical calculations dealing with the equilibrium geometries, electronic-state patterns and evolutions, harmonic and anharmonic wavenumbers of the monomer and dimer, either neutral or positively charged. The state energies of the [δ-valerolactam]+ cation in the equation image ground, equation image, equation image and equation image excited electronic states, and of the [δ-valerolactam]2+ cation′s lowest states are determined. After its formation, [δ-valerolactam]2+ is subject to intramolecular isomerization, H transfer and then unimolecular fragmentation processes. Close to the ionization thresholds, the photoionization of these molecules is found to be mainly dominated by a direct process whereas the indirect route (autoionization) contributes at higher energies.

Abstract

We have investigated the dissociation of alpha- and beta- alanine following impact of slow multicharged ions, namely He(+), He(2+), O(5+) and Xe(20+) at 10 keV per charge unit. The collision products were analyzed using a reflectron-type time-of-flight mass spectrometer. In general, for a given projectile, ionization of both alanine-isomers gives rise to similar fragmentation patterns. However, significantly different peak intensities are observed for fragments with mass over charge ratios (m/q) of 30 and 44 amu. These differences can be explained in terms of isomer geometry and fragment stability. By analyzing the fragment kinetic energies, we found that protons as well as ionic oxygen fragments are sufficiently energetic (up to 200 eV for Xe(20+)) to induce further damage in a biological environment.

Abstract

International audience; Beams of low-energy ions are specific tools for interdisciplinary research allowing for preparing and studying the properties of complex systems like (bio)molecules, clusters and surfaces. In particular highly charged ions can induce strong electronic excitations as they are carriers of a large amount of potential energy up to the high keV range. But also other types of ion beams, like size-selected cluster beams or beams of biomolecular species, are useful for preparing and structuring surfaces or performing collision experiments. The ARIBE facility, located in Caen, which is part of the distributed European Facility LEIF, delivers such types of beams. In the present contribution recent technical developments and typical results are discussed.

Abstract

International audience; We demonstrate how combining highly-charged ions and exotic atoms measurements can provide high-accuracy information on particle properties, like the pion mass, on interactions, like the pion-proton strong interaction at low energy, and bound-state QED in strong fields. The use of highly-charged ion X-rays emitted by the plasma inside a super-conducting ion source provides a very detailed characterization of the response function of the X-ray spectrometer used to study exotic atoms, allowing for very accurate measurements. Conversely the use of the same high-resolution and high transmission spectrometer provides very accurate measurements of X-ray lines of few-electron ions.
