Publikováno v: Astronomy and Astrophysics-A&A
Astronomy and Astrophysics-A&A, EDP Sciences, 2020, 640, pp.A115. ⟨10.1051/0004-6361/202037926⟩

Aims. The aim of this work is to provide semi-empirical branching ratios (BRs) for the kinetic databases used in astrochemistry, such as the KInetic Database for Astrochemistry (KIDA). Our work focuses on the CHy(+) species (y = 2–4) excited by cos

Synopsis We are studying small hydrocarbons produced in high velocity (3.4 a.u.) collision between CH y + cations and He atoms. During the collision those hydrocarbons gain some energy and release this energy doing fragmentation. Thanks to the detect

Energy deposit by electron excitation in CnN+ projectiles (n=1-3) colliding at in termediate velocity with He atoms : semi-empirical estimates and calculations

Autor: S Diaz-Tendero, T Idbarkach, T Mahajan, A. Jorge, K. Béroff, Néstor F. Aguirre, Marin Chabot, C Illescas, B Pons

Publikováno v: Journal of Physics: Conference Series. 1412:142026

Synopsis Using measured dissociation branching ratios and theoretical dissociation energies, we extracted semi-empirical estimates of the energy deposit due to electron excitation in CnN+-He collisions at v=2.2 a.u. We compared these estimates to cal
