Alexander Kramida is interested in the analysis of spectra of neutral and ionized atoms and is active in the critical compilation of atomic spectral data for NIST’s atomic spectroscopy databases. He is currently involved in evaluation of energy levels, wavelengths, and transition probabilities in several spectra of atoms and atomic ions, and critical evaluation of experimental and theoretical ionization energies of all stages of ionization of all chemical elements. Utilizing his knowledge of computer programming, he assists in support of the online databases on atomic spectra.
