Electronic spectroscopy of cold ions in a radio-frequency trap [PDF]
, 2010 The low density of ions in mass spectrometers generally precludes direct absorption measurements. The spectrum of ions can nonetheless be obtained by using resonance two-color photofragmentation or multiphoton photofragmentation techniques.

Isotope dependence of the Zeeman effect in lithium-like calcium
Nature Communications, 2016 In addition to hyperfine splitting effects, isotope shifts of atomic electronic energy levels allow the investigation nuclear properties. Here, the authors study the isotope dependence of the Zeeman effect in litihium-like calcium isotopes in a Penning ...

Effect of the doping level on the 2.8-µm laser performance of Er3+:CaF2 crystals [PDF]
EPJ Web of ConferencesThe effect of doping level (0.1-10 at.%) on mid-infrared laser performance of Er:CaF2 crystals was investigated. The Er:CaF2 laser delivered 1.17 W at 2798 nm with 35.8% slope efficiency and was tuned across 2690-2830 nm.

VUV/EUV ionising radiation and atoms and ions: dual laser plasma investigations [PDF]
, 2004 The interaction of ionising radiation with atoms and ions is a key fundamental process. This report concentrates on studies of photoexcitation/photoionisation using laser-produced plasmas as continuum sources and synchronised laser plasma plumes to ...

Clustering of ions at atomic dimensions in quantum plasmas
, 2013 By means of particle simulations of the equations of motion for ions interacting among themselves under the influence of newly discovered Shukla–Eliasson attractive force (SEAF) in a dense quantum plasma, we demonstrate that the SEAF can bring ions ...

Solvolyses of diarylmethyl chlorides. A comprehensive stability scale for diarylcarbenium ions [PDF]
, 1988 Eleven donor substituted diarylmethyl chlorides have been solvolyzed in ethanol. The rate constants, determined at 25°C, and additional ethanolysis data taken from the literature have been connected with solvolvsis rate constants, determined in other ...
