Note: Micro-channel array crucible for isotope-resolved laser spectroscopy of high-temperature atomic beams Open
We present a novel compact design for a multichannel atomic oven which generates collimated beams of refractory atoms for fieldable laser spectroscopy. Using this resistively heated crucible, we demonstrate spectroscopy of an erbium sample…

Evaluation of the exothermicity of the chemi-ionization reaction Sm + O → SmO+ + e− Open
The exothermicity of the chemi-ionization reaction Sm + O → SmO+ + e− has been re-evaluated through the combination of several experimental methods. The thermal reactivity (300–650 K) of Sm+ and SmO+ with a range of species measured using …
