CALCULATED WAVELENGTHS FOR TRANSITIONS BETWEEN S AND P STATES IN 2-ELECTRON ATOMS AND COMPARISON WITH EXPERIMENT

Theoretical wavelengths are calculated for the 2S1-2P1 and the 3P3-4S3 transitions in CV, and for the 2S3-3P3, 2S3-4P3 and 2S3-5P3 transitions in CV, NVI, and OVII. The theoretical wavelengths are compared with the results of recent measurements using laser-produced plasmas. When the mass-polarization and relativistic effects are included, the calculations agree with the experimental results in most cases, and thus assist in verifying the identification of some new spectral lines. © 1969 The American Physical Society.
