UV light from the ground term of Ti-like ytterbium, tungsten, and bismuth

We have used an electron-beam ion trap to measure the wavelength of the J=2-3 magnetic dipole transition in the 3d{sup 4} ground term of Ti-like ytterbium, tungsten, and bismuth. This fills in a gap in previous measurements along this isoelectronic sequence, as well as extending previous work to the highest Z yet. With the addition of our results, measurements of this line now cover a sufficient range of Z to allow an interpolation of reliable wavelength estimates for the unmeasured members of the isoelectronic sequence from Z=52 to 83. We provide a table of these wavelengths for each member of the sequence in this range, and compare the measured wavelengths to recent calculations. Our results show that a long-standing discrepancy between prediction and experiment disappears in the high-Z limit. (c) 2000 The American Physical Society.
