TL;DR: In this paper, it was shown that the dianion yield depends on the size of the fullerenes with more than 10% of the trapped C90- ions forming dianions while the corresponding relative yield was less than 0.1%.

TL;DR: The Penning trap mass spectrometer ISOLTRAP plays a leading role in mass-spectrometry of short-lived nuclides as discussed by the authors, and the recent installation of a radio-frequency quadrupole trap and a carbon cluster ion source allowed for the first time mass measurements on exotic nuclei with a relative uncertainty of δ m / m ≈ 1×10 −8.

TL;DR: In this article, the ions from a quasi-continuous source are bunched in a linear radio-frequency quadrupole ion trap, separated by a multi-reflection time-of-flight section followed by a Bradbury-Nielsen gate, and then captured in a Penning trap.

TL;DR: In this paper, it was shown that the observed delayed electron emission is a thermal process in analogy to thermionic emission of bulk materials, and that the dominating cooling channel of laser excited clusters generally occurs as long as the electron binding energy is lower than the dissociation energy.

TL;DR: In this article, a two-electrode ion trap consisting of concentric single-sheet hyperboloids has been constructed and experimentally tested for Fourier transform ion cyclotron resonance mass spectrometry.
