Abstract

This work describes the application of the technique of photographic VUV spectroscopy to accurate measurement of the wavelength of the theoretically interesting 1s2s ³S₁-1s2p ³P₂ transition in helium-like Ne⁸⁺ in a recoil ion source. Good resolution is obtained, and a preliminary value of 124.815±0.002 nm is found for the wavelength.

Spectroscopy of heliumlike ions is discussed putting emphasis on mid and high Z atoms. Experimental aspects of ion charge, excitation production, clean spectra, and precise wavelength measurement are detailed. Recent results obtained at several laboratories including Lyon, Argonne, Notre-Dame, Oxford, Berkeley, Darmstadt, Paris, are used to test the QED contributions and higher order relativistic corrections to two-electron atom energies.
A differential measurement of the ground state Lamb shift in hydrogenic germanium, Ge31+
1988, Nuclear Inst. and Methods in Physics Research, B
The 1s-2p Lyman α transitions in hydrogenic germanium, Ge³¹⁺, have been observed in fourth order of diffraction from a beam-foil light source, simultaneously with the n = 2 to n = 4 Balmer β transitions observed in first order of diffraction. This enables a measurement of the Lyman α wavelengths using the Balmer β wavelengths as a calibration. The results are presented, along with a discussion of the experimental errors, and further work which should improve the accuracy with which the Lyman α. wavelengths can be determined.
