Journal ArticleDOI
Spectroscopic absorption measurements of an iron plasma.
P. T. Springer,D. J. Fields,Brian G. Wilson,J. K. Nash,William H. Goldstein,Carlos A. Iglesias,Forrest J. Rogers,J. K. Swenson,M. H. Chen,A. Bar-Shalom,Richard E. Stewart +10 more
TL;DR: The first quantitative measurement of photoabsorption in the region determining the Rosseland and Planck mean opacities is obtained for a well-characterized, radiatively heated iron plasma using new techniques and instrumentation.
Journal ArticleDOI

TL;DR: Results of a niobium absorption experiment are presented that represent a major step in the development of techniques necessary for the quantitative characterization of hot, dense matter.
Journal ArticleDOI
Structure and Lamb shift of 2s1/2-2p3/2 levels in lithiumlike U89+ through neonlike U82+
TL;DR: The first Doppler-shift-free crystal-spectrometer measurement of stationary highly stripped uranium ions from a high-energy electron beam ion trap is presented, providing benchmarks for testing relativistic correlation and quantum electrodynamic effects in highly charged multielectron ions.
Journal ArticleDOI
Dielectronic recombination of heliumlike ions.
TL;DR: The x rays emitted during dielectronic recombination by ions in an electron-beam ion trap are observed and cross sections from a calibration based upon radiative recombination generally agree well with theoretical predictions.
Journal ArticleDOI
Observation of interference between dielectronic recombination and radiative recombination in highly charged uranium ions.
TL;DR: High-resolution measurements of photon excitation functions for radiative recombination and dielectronic recombination in highly charged uranium ions show evidence for quantum interference between the two processes in the vicinity of the [ital KLL] resonances.
