Abstract

We have used an electron beam ion trap (EBIT) to measure the wavelength of the J=2 to j=3 magnetic dipole transition in the 3d4 ground term of Ti-like Ytterbium and Tungsten. These results extend the range of measurements of this line along the isoelectronic sequence into a region where calculations have indicated that the wavelength increases with increasing atomic number Z. We see no evidence for such retrograde Z dependence in our measurements. Measurements of this line now cover a sufficient range of Z that the smooth discrepancy between recent calculations and experiments can be interpolated to provide accurate wavelength estimates for the unmeasured members of the isoelectronic sequence form Z=52 to Z=82. We provide a table of these wavelengths for each member of the sequence in this range.
