Observation of the 162 Dy- 164 Dy Isotope Shift for the 0 → 16 717.79 cm -1 Optical Transition.
APPLIED SPECTROSCOPY(2017)
Abstract
In this work, we report a newly observed isotope shift between Dy-162 and Dy-164 isotopes for the 0 16717.79cm(-1) (598.003nm) optical transition. We compared the newly observed results against two other lines (597.452nm and 598.859nm), which we measured in this work, and were already reported in the literature. The newly observed 162-164 Dy isotope shift, shows at least a 20% larger isotope shift than the isotope shifts for the other two lines investigated. The larger 162-164 isotope shift observed for the 598.003nm line could lead to an increased isotope selectivity for atomic vapor laser isotope separation (AVLIS). Hence, this line could be a good choice for application in AVLIS. Experimental data available in the literature for the 597.452nm and 598.859nm lines, enabled us to perform simulations of spectra for both lines, in order to confirm the accuracy of our experimental measurements.
