Beam-laser measurements of the lifetimes of the 6p levels in Yb II
Abstract
Results are presented for the lifetimes of the 6p levels in Yb II, viz., 8.07+/-0.09 ns for the j=12 level and 6.15+/-0.09 ns for the j=32 level. These are compared with previous experiments and calculations. Our values are in excellent agreement with previous experiments, but show a significant improvement in precision. The results from previous calculations show a rather wide scatter but the experimental values are still consistent with the means of the calculated values within that scatter. However, there does still appear to be a need for a more complete calculation for the Yb+ ion.
