Extension of the resonance line series of Mg III

December 1, 2009
Author(s)
C M. Brown, Alexander Kramida, Uri Feldman, Joseph Reader
Spectra of Mg emitted by a Penning discharge were recorded in the extreme ultraviolet (EUV) on a 10.7-m grazing-incidence spectrograph with phosphor image plates. The spectra provided nine new lines of Mg III between 156 and 166 Å and allowed us to improve

Phases of a 2D Bose Gas in an Optical Lattice

September 9, 2010
Author(s)
Karina K. Jimenez Garcia, Yu-Ju Lin, James V. Porto, Ian B. Spielman
Ultra-cold atoms in optical lattices realize essential models in condensed matter physics. Like with most experiments with ultra-cold atoms, our Rubidium-87 Bose Einstein condensate is confined in a harmonic trapping potential that persists even when

Competitive solvation effects in polyelectrolyte solutions

Alexandros Chremos, Jack F. Douglas
… of the competitive association of water (“hydration”) and ion association to the polymer backbone and the consequences … due to the high polarizability of this diffuse counter-ion cloud. We investigate the influence of counter-ion affinity for polyelectrolyte segments on the …

Thermal-hydraulic Assessment of the Proposed NIST Neutron Source Design

October 6, 2023
Author(s)
Anil Gurgen, Abdullah Weiss, Joy Shen
To replace the ageing reactor at the NIST Center for Neutron Research, a new reactor design is proposed, namely the NIST Neutron Source or NNS. The NNS will contain a light-water moderated and cooled core that would serve as a neutron source for a state-of
