Spectroscopic diagnostics of low-ionized iron-peak elements. Electron-impact excitation of Ni and photoionisation of Ni
Luis Fernández-Menchero, Ryan T. Smyth, Catherine A. Ramsbottom +1
The spectra from Fe-peak elements may be used to determine the temperature and density of various astrophysical objects. Determination of these quantities is underpinned by the acc…
Dirac R-matrix calculations for the electron-impact excitation of neutral tungsten providing noninvasive diagnostics for magnetic confinement fusion
R. T. Smyth, C. P. Ballance, C. A. Ramsbottom +3
Neutral tungsten is the primary candidate as a wall material in the divertor region of the International Thermonuclear Experimental Reactor (ITER). The efficient operation of ITER…
A Quantitative Comparison of Opacities Calculated Using the Distorted- Wave and -Matrix Methods
F. Delahaye, N. R. Badnell, C. P. Ballance +7
The present debate on the reliability of astrophysical opacities has reached a new climax with the recent measurements of Fe opacities on the Z-machine at the Sandia National Labor…
