TL;DR: The velocity imaging photoionisation coincidence (VIPCO) technique is shown to be a powerful tool for studies of ion pair formation.

TL;DR: In this article, the velocity imaging photoionisation coincidence (VIPCO) technique is applied to the photoionization of CO into the inner-valence 4 2 Σ+ state of CO+, and the molecular frame photoelectron angular distributions are measured on the high energy side of the known σ* shape resonance.

TL;DR: In this paper, the energy resolution and detection efficiency of a magnetic bottle electron spectrometer equipped with an electrostatic retarder were examined, with a particular focus on its application to electron coincidence measurements.

TL;DR: In this paper, the transition region for the photodissociation reaction was discussed, especially being focused on the nature of the primary molecular states and their dynamical aspects including competitive molecular autoionization.

TL;DR: In this paper, the authors studied single photon double K-shell ionization of small molecules and the Auger decay of the resulting double core hole (DCH) molecular ions thanks to multi-electron coincidence spectroscopy using a magnetic bottle time-offlight spectrometer.
