Visible line intensities of the triatomic hydrogen ion from experiment and theory
Annemieke Petrignani, Max H. Berg, Florian Grussie +7
The visible spectrum of H3+ is studied using high-sensitivity action spectroscopy in a cryogenic radiofrequency multipole trap. Advances are made to measure the weak ro-vibrational…
The Low-Temperature Nuclear Spin Equilibrium of H3+ in Collisions with H2
F. Grussie, M. H. Berg, K. N. Crabtree +5
Recent observations of H2 and H3+ in diffuse interstellar sightlines revealed a difference in the nuclear spin excitation temperatures of the two species. This discrepancy comes as…
Resonant structure of low-energy H3+ dissociative recombination
Annemieke Petrignani, Simon Altevogt, Max H. Berg +17
New high-resolution dissociative recombination rate coefficients of rotationally cool and hot H3+ in the vibrational ground state have been measured with a 22-pole trap setup and a…
Energy-sensitive imaging detector applied to the dissociative recombination of D2H+
H. Buhr, M. B. Mendes, O. Novotný +12
We report on an energy-sensitive imaging detector for studying the fragmentation of polyatomic molecules in the dissociative recombination of fast molecular ions with electrons. Th…
Anisotropic fragmentation in low-energy dissociative recombination
S. Novotny, H. Rubinstein, H. Buhr +18
On a dense energy grid reaching up to 75 meV electron collision energy the fragmentation angle and the kinetic energy release of neutral dissociative recombination fragments have b…
Spectroscopy and dissociative recombination of the lowest rotational states of H3+
A. Petrignani, H. Kreckel, M. H. Berg +13
The dissociative recombination of the lowest rotational states of H3+ has been investigated at the storage ring TSR using a cryogenic 22-pole radiofrequency ion trap as injector. T…
