    • Nitrogen K-Shell Photoabsorption 

      Garcia, J.; Kallman, T. R.; Witthoeft, M.; Behar, E.; Mendoza, C.; Palmeri, P.; Quinet, P.; Bautista, M. A.; Klapisch, M. (IOP PUBLISHING LTD, 2009-12)
      Reliable atomic data have been computed for the spectral modeling of the nitrogen K lines, which may lead to useful astrophysical diagnostics. Data sets comprise valence and K-vacancy level energies, wavelengths, Einstein ...
    • Radiative and Auger Decay Data for Modeling Nickel K Lines 

      Palmeri, P.; Quinet, P.; Mendoza, C.; Bautista, M. A.; Garcia, J.; Witthoeft, M. C.; Kallman, T. R. (IOP PUBLISHING LTD, 2008-12)
      Radiative and Auger decay data have been calculated for modeling the K lines in ions of the nickel isonuclear sequence, from Ni(+) up to Ni(27+). Level energies, transition wavelengths, radiative transition probabilities, ...
    • Radiative transition rates and collision strengths for Si II 

      Bautista, M. A.; Quinet, P.; Palmeri, P.; Badnell, N. R.; Dunn, J.; Arav, Nahum (EDP SCIENCES, 2009-12)
      Aims. This work reports on radiative transition rates and electron impact excitation collision strengths for levels of the 3s(2)3p, 3s3p(2), 3s(2)4s, and 3s(2)3d configurations of Si II. Methods. The radiative data were ...
    • Spectrum Synthesis Modeling of the X-Ray Spectrum of GRO J1655-40 Taken During the 2005 Outburst 

      Kallman, T. R.; Bautista, M. A.; Goriely, S.; Mendoza, C.; Miller, J. M.; Palmeri, P.; Quinet, P.; Raymond, J. (IOP PUBLISHING LTD, 2009-08)
      The spectrum from the black hole X-ray transient GRO J1655-40 obtained using the Chandra High Energy Transmission Grating in 2005 is notable as a laboratory for the study of warm absorbers, and for the presence of many ...
