Abstract

From an absolute wavelength measurement of the

2 s {}^{3}S_{1} - 2 p {}^{3}P_{1}

transition in

{}^{7}{Li}

II we deduce a Lamb shift of 1.274±0.015

{cm}^{- 1}

, compared with a theoretical value of 0.99±0.04

{cm}^{- 1}

for the

2 s {}^{3}S_{1}

level. We suggest that the difference is due to a Lamb shift of the

2 p {}^{3}P_{1}

level and show that other measurements in isoelectronic two-electron spectra are in accord with this prediction.
