The difference between the frequency of the 2S-4P 1/2 transition and a quarter of the 1S-2S transition frequency in atomic hydrogen has been measured by high-resolution laser spectroscopy. The result is 4696.3 (2.0) MHz, from which the value 8168 (8)

The authors report the observation of the 1S-2S two-photon transition in atomic hydrogen in an atomic beam, excited by light from a narrow-band continuous-wave laser. The excitation takes place in a collision-free environment and detection of the res

The authors show that it is valid to use the value of the non-relativistic quantity mod psi (0) mod 2 obtained from a measurement of hyperfine structure (HFS) in the interpretation of field isotope shifts (FS) using conventional theory, in so far as

The quadratic Stark effect in the hyperfine structure of the 2 P ½ ground level of aluminium has been investigated by the method of atomic beams. A frequency shift caused by the application of an electric field has been interpreted in terms of an ef

Isotope shifts and pressure broadening have been measured in the two-photon transition at 249 nm from the 5p6 1S0 ground level of neutral xenon to a J=0 level of the 5p56p configuration (the 2p5 level in Paschen notation). A continuous-wave tunable d

The theory of the field isotope shift (FS) in atomic spectra is discussed critically and the results are presented in a form which is more straightforward than the expressions traditionally used to interpret experimental data. First-order perturbatio
