High-Precision Determination of Oxygen-K Transition Energy Excludes Incongruent Motion of Interstellar Oxygen
M. A. Leutenegger, S. Kühn, P. Micke +25
We demonstrate a widely applicable technique to absolutely calibrate the energy scale of x-ray spectra with experimentally well-known and accurately calculable transitions of highl…
High-resolution Charge Exchange Spectra with L-shell Nickel Show Striking Differences from Models
G. L. Betancourt-Martinez, P. Beiersdorfer, G. V. Brown +7
We present the first high-resolution laboratory spectra of X-ray emission following L-shell charge exchange between nickel ions and neutral H2 and He. We employ the commonly used c…
X-ray resonant photoexcitation: line widths and energies of Kα transitions in highly charged Fe ions
J. K. Rudolph, S. Bernitt, S. W. Epp +14
Photoabsorption by and fluorescence of the Kα transitions in highly charged iron ions are essential mechanisms for X-ray radiation transfer in astrophysical environments. We study…
Measurement of anomalously strong emission from the 1s-9p transition in the spectrum of H-like phosphorus following charge exchange with molecular hydrogen
M. A. Leutenegger, P. Beiersdorfer, G. V. Brown +3
We have measured K-shell x-ray spectra of highly ionized argon and phosphorus following charge exchange with molecular hydrogen at low collision energy in an electron beam ion trap…
EBIT Charge-Exchange Measurements and Astrophysical Applications
B. J. Wargelin, P. Beiersdorfer, G. V. Brown
The past decade has seen a surge of interest in astrophysical charge exchange (CX). The impetus was the discovery of X-ray emission from comets in 1996, soon followed by the observ…
Laboratory simulation of cometary x rays using a high-resolution microcalorimeter
P. Beiersdorfer, H. Chen, K. R. Boyce +5
X-ray emission following charge exchange has been studied on the University of California Lawrence Livermore National Laboratory electron beam ion traps EBIT-I and EBIT-II using a…
