Identifications of extreme ultraviolet spectra of Br-like to Ni-like neodymium ions using an electronbeam ion trap

April 30, 2021

Author(s)

C. Suzuki, Dipti Goyal, Y. Yang, A. Gall, Roshani Silwal, S. Sanders, Aung S. Naing, Joseph N. Tan, Endre A. Takacs, Yuri Ralchenko

Charge-resolved extreme ultraviolet spectra of open N-shell neodymium (Nd) ions have been recorded in an electron beam ion trap facility at the National Institute of Standards and Technology. The measurements have been performed for nominal electron beam

Complete collision data set for electrons scattering on molecular hydrogen and itsisotopologues: I. Fully vibrationally-resolved electronic excitation of H 2 (X 1 ? g + ).

Yuri Ralchenko, Alexander Kramida

Over the last 25 years, the atomic standard reference databases and online tools developed at the National Institute of Standards and Technology (NIST) provide users around the world with the highest-quality data on various atomic parameters (e.g., level

Measurements of the Linear Polarization of Satellite Transitions from Li- and Be- like Ar Ions

Amy Gall, Dipti Goyal, Sean W. Buechele, Samuel C. Sanders, Roshani Silwal, Csilla I. Szabo-Foster, N Brickhouse, Yuri Ralchenko, Endre A. Takacs

Non-thermal electron distributions, such as beams of electrons, are found in many laboratory and astrophysical plasma sources and can produce anisotropic and polarized emission. Theories used to model the emission require sublevel specific analysis, which
