Abstract: | Using a tunable single mode dye laser the isotope shift of the 573.7 nm-line between the isotopes Lu175 and Lu176 has been determined to be IS(176?175, 573.7 nm)=?394(5) MHz yielding a change of mean square nuclear radii ofδ〈r 2〉=0.022(5) fm2. In addition from our measurements the following values of the hyperfine splitting constantsA andB could be deduced Lu176 5d6s6p 4 F 3/2:A=?651.4(0.3) MHz,B=2,494(4) MHz 5d6s 2 2 D 3/2:A=138.0(0.3) MHz,B=2,131(3) MHz Lu175 5d6s6p 4 F 3/2:A=?924.7(0.5) MHz,B=1,767(4) MHz. |
