Adaptable platform for trapped cold electrons, hydrogen and lithium anions and cations
Levi O. A. Azevedo, Rodolfo J. S. Costa, Wania Wolff +4
Cold cations, electrons and anions are ubiquitous in space, participate in star formation chemistry and are relevant to studies on the origin of molecular biology homochirality. We…
Investigation of the Carbon Monoxide Dication Lifetime Using (CO) Dimer Fragmentation
A. Méry, X. Fléchard, S. Guillous +5
The fragmentation of carbon monoxide dimers induced by collisions with low energy Ar ions is investigated using the COLTRIMS technique. The presence of a neighbor molecule i…
Coulomb explosion imaging of carbon monoxide dimers
A. Méry, V. Kumar, X. Fléchard +6
We report on experimental results obtained from collisions of slow highly charged Ar9+ ions with a carbon monoxide dimer (CO)2 target. A COLTRIMS setup and a Coulomb explosion imag…
Low-temperature chemistry induced by cosmic rays: positive and negative ions desorption from nitrile-bearing astrophysical ice analogues
Fabio de A Ribeiro, Guilherme C Almeida, Wania Wolff +3
In cold core of dark molecular clouds, where the UV radiation from external sources is strongly attenuated, cosmic rays can induce chemical reactions on the surface of ice-covered…
Destruction and multiple ionization of PAHs by X-rays in circumnuclear regions of AGNs
Thiago Monfredini, Heidy M. Quitián-Lara, Felipe Fantuzzi +6
The infrared signatures of polycyclic aromatic hydrocarbons (PAHs) are observed in a variety of astrophysical objects, including the circumnuclear medium of active galactic nuclei…
Ionisation and dissociation of cometary gaseous organic molecules by solar wind particles I: Formic Acid
S. Pilling, A. C. F. Santos, W. Wolff +5
In order to simulate the effects of energetic charged particles present in the solar wind colliding with the cometary gaseous formic acid molecule (HCOOH), laboratory experiments h…
