Abstract
We have calculated radiative and Auger transition rates, x-ray wavelengths, lifetimes, and fluorescence yields of variously ionized calcium atoms with electronic configurations 1s2sm2pn, (m=0−2, n=1−6) with all allowed values of the orbital angular momentum quantum number l. The calculation was performed in the intermediate coupling scheme using the Hartree-Fock atomic model. The results from the present calculation have been compared with those available in the literature. Excellent agreement is found in calculated transition energies among the various calculations. The agreement in transition rates is generally good for prominent lines. The radiative and Auger transition rates decrease as electrons are removed from the outer shells. The rate of decrease of Auger transition rates, however, is faster than that of radiative transition rates. The fluorescence yields are found to increase with ionization.
