Abstract

A measurement of the hyperfine coefficients and isotope shifts for the atomic dysprosium 421.291 nm transition ( 4 f 10 6 s 2 , J = 8 4 f 10 6 s 6 p , J = 9 ) using atomic beam laser-induced fluorescence spectroscopy is presented. A King plot analysis is performed to determine a specific mass shift of δ ν sms 164 162 = 11 ( 7 ) MHz for the 421 nm transition, confirming the pure 4 f 10 6 s 6 p configuration of the excited state. This transition is currently being explored for laser cooling of an atomic beam of dysprosium used in a search for a temporal variation of the fine-structure constant.
