Effects of indirect processes on the X-ray spectra of the Ca XVI ions

摘要

The X-ray spectra of B-like Ca ions are calculated under the assumption of the none local thermal dynamical equilibrium by using the relativistic multi-configuration atomic package FAC. The effects of indirect processes on the X-ray spectra of the B-like Ca ions are studied. These processes include collision, ionization, radiative recombination, dielectronic recombination, and resonance excitation. Three models are used to simulate the X-ray spectra. We find that these indirect processes are important to calculate the X-ray spectra of the B-like Ca ions.
