Three lines in the atomic spectrum of tin, λ 3262 Å, λ 3283 Å and λ 6454Å have been studied in emission under high resolution with the use of light sources containing enriched isotopic samples. Results are reported for isotope shifts in these lines for the abundant stable isotopes ( A ≽ 116). Pressure-scanned Fabry–Perot etalons provided the necessary resolution; the spectrograms for λ 6454 Å were recorded and analysed by digital techniques, and for this line hyperfine structure constants required in the interpretation of the data were also evaluated. The results for the three lines are not in good agreement with earlier work, but are shown to be self-consistent by means of a King plot. Their interpretation in terms of the nuclear charge distribution is considered in the following paper.

A simple empirical relation for the estimation of the correlation energy (Ecorr) is found to be valid for the isoelectronic series of Be- and Ne-like ions to a very good accuracy. Although originally such a relation was proposed for the He-like ions, the present results indicate that it is applicable for layer systems as well. Thus the interelectron pair correlation in systems such as Be or Ne does not affect adversely the accuracy of the relation:[Formula: see text]where the denominator is the size [Formula: see text] weighted by the square of the effective nuclear charge Zeff.
