Abstract
EN In this work a preliminary feasibility study of the possibilities of laser cooling for the terbium atom was performed. Possible first- and second-stage cooling transitions were considered. For each of them semi-empirical estimation of the branching ratios and the lifetimes of the upper levels was performed. These should be regarded as rough estimates only, and certainly require experimental verification (planned in the future). The spectral lines proposed for possible second-stage cooling transitions were recorded by laser spectroscopy in a hollow cathode discharge lamp to confirm their hyperfine structure patterns and verify the hitherto known values of the constants and . Suitable hyperfine structure components for cooling and hyperfine repumping were indicated. A possible application of two of the transitions considered for a system for electromagnetically induced transparency, based on the hyperfine structure, is also suggested.
