Collisional excitation of H $_{2}$ CO by He: Experimental validation of state-of-the-art scattering calculations

Chinmai Sai Jureddy, Sandor Demes, Francesca Tonolo +2

Context. Non-local thermodynamic equilibrium conditions in the interstellar medium require collisional rate coefficients to model astronomical observations; these are usually deter…

Dissociative recombination of N $_{2}$ H $^{+}$ : Isotopic effects

J. Zs. Mezei, A. Orban, S. Demes +4

The investigation of the isotopic ratio of interstellar nitrogen -- $^{14}$ N versus $^{15}$ N -- is done, for explaining its variations observed for N2H+ in different interstellar a…

Rotational excitation cross sections for chloronium based on a new 5D interaction potential with molecular hydrogen

SÃ¡ndor Demes, Dariusz KÄdziera, Alexandre Faure +1

Chloronium (H $_{2}$ Cl $^{+}$ ) is an important intermediate of Cl-chemistry in space. The accurate knowledge of its collisional properties allows a better interpretation of the correspon…
