ENERGY-LEVELS OF CALCIUM, CA-I THROUGH CA-XX

The energy levels of the calcium atom in all of its stages of ionization, as derived from the analyses of atomic spectra, have been critically compiled. In cases where only line classifications are reported in the literature, level values have been derived. Electron configurations, term designations, J‐values, experimental g‐values, and ionization energies are included. Calculated percentages of the two leading components of the eigenvectors of the levels are given. © 1979, American Institute of Physics for the National Institute of Standards and Technology.
