Coherent spectroscopy of collective excitations in superfluid helium far from equilibrium
Gabriel Voith, Alexander A. Milner, Michael J. Desrochers +2
Ultrafast dynamics of collective excitations in superfluids remains largely unexplored beyond the roton region of the Landau excitation spectrum, despite the importance of such dyn…

Atomic Transition Probabilities for UV and Optical Lines of Gd II
G. T. Voith, E. A. Den Hartog, I. U. Roederer
We report new branching fraction measurements for 156 ultraviolet and optical transitions of Gd II. These transitions range in wavelength (wavenumber) from 2574 to 6766 Angstroms (…

Atomic Transition Probabilities for UV and Optical Lines of Tm II
E. A. Den Hartog, G. T. Voith, I. U. Roederer
We report new branching fraction measurements for 224 ultraviolet (UV) and optical transitions of Tm II. These transitions range in wavelength (wavenumber) from 2350 - 6417 Angstro…
