Bombardment of CO ice by cosmic rays: I. Experimental insights into the microphysics of molecule destruction and sputtering
Alexei V. Ivlev, Barbara M. Giuliano, Zoltán Juhász +12
We present a dedicated experimental study of microscopic mechanisms controlling radiolysis and sputtering of astrophysical ices due to their bombardment by cosmic ray ions. Such io…
Proton and electron irradiations of CH4:H2O mixed ices
Duncan V. Mifsud, Péter Herczku, Béla Sulik +7
The organic chemistry occurring in interstellar environments may lead to the production of complex molecules that are relevant to the emergence of life. Therefore, in order to unde…
Thermodynamic model for electron emission and negative- and positive-ion formation in keV molecular collisions
Zoltán Juhász
A statistical-type model is developed to describe the ion production and electron emission in collisions of (molecular) ions with atoms. The model is based on the Boltzmann populat…
Anion emission from water molecules colliding with positive ions: Identification of binary and many-body processes
J. -Y. Chesnel, Z. Juhász, E. Lattouf +9
It is shown that negative ions are ejected from gas-phase water molecules when bombarded with positive ions at keV energies typical of solar-wind velocities. This finding is releva…
Formation of negative hydrogen ions in 7-keV OH+ + Ar and OH+ + acetone collisions: a general process for H-bearing molecular species
Zoltán Juhász, Béla Sulik, Jimmy Rangama +4
We demonstrate that the formation of negative hydrogen ions (H-) occurs in a wide class of atomic and molecular collisions. In our experiments, H- emission from hydroxyl cations an…
Formation of anions and cations via a binary-encounter process in OH + Ar collisions: the role of dissociative excitation and statistical aspects
E. Lattouf, Z. Juhász, J. -Y. Chesnel +8
Molecular fragmentation leading to the formation of negatively and positively charged hydrogen ions in 7-keV OH + Ar collisions is investigated experimentally. The most strikin…
