The laboratory measurement of processes in- volved in terrestrial airglows is essential in developing di- agnostic tools of the dynamics and photochemistry of the upper atmosphere. Dissociative electron recombination of O + in the ionospheric F-regio

This paper describes a novel method to experimentally determine the net amount of internal energy deposited into biomolecules during sustained off-resonance irradiation collision-induced dissociation (SORI-CID). The method of calibration is based on

We present experimental data on the dissociative recombination (DR) and the dissociative excitation (DE) of O2+ in its electronic and vibrational ground state using a heavy ion storage ring. The absolute DR cross section has been determined over an e
