Ion processes across cosmic times (C04)

• Subject Area: Astrophysics and Astronomy
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 500700252

Project C4 aims at recording high-resolution rotational-vibrational as well as pure rotational spectra of molecular ions. Additionally, we want to study the energetics and kinetics of their low-temperature reactions with simple neutral collision partners, providing important rate coefficients for astrochemical models. Prime targets of this endeavour are molecular ions formed at early stages of cosmic evolution, e.g., those containing mainly hydrogen and helium. In particular, the fundamental ions HHe+n, H2He+n and the loosely bound H+3 – He shall be investigated at cryogenic temperatures.
