Improved Fe II emission line models for AGN using new atomic datasets
A. Sarkar, G. J. Ferland, M. Chatzikos +6
Understanding the Fe II emission from Active Galactic Nuclei (AGN) has been a grand challenge for many decades. The rewards from understanding the AGN spectra would be immense, inv…
Advances in neutral tungsten ultraviolet spectroscopy for the potential benefit to gross erosion diagnosis
C. A. Johnson, D. A. Ennis, S. D. Loch +8
A spectral survey of tungsten emission in the ultraviolet region has been completed in the DIII-D tokamak and the CTH torsatron to assess the potential benefit of UV emission for t…
Radiative association of atomic and ionic carbon
James F. Babb, R. T. Smyth, B. M. McLaughlin
We present calculated cross sections and rate coefficients for the formation of the dicarbon cation (C) by the radiative association process in collisions of a C atom…
Dicarbon formation in collisions of two carbon atoms
James F. Babb, R. T. Smyth, B. M. McLaughlin
Radiative association cross sections and rates are computed, using a quantum approach, for the formation of C molecules (dicarbon) during the collision of two ground state C($^…
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…
