We have used a new collinear laser-ion beam technique to measure the radiative lifetime of the 6 p 4 P 5 2 0 level in Xe II. Our result of 7.95±0.16 ns is in disagreement with previous results. The appartus was tested by making a similar measurement

Levels in 189, 191, 193Au have been studied by radioactive decay of isotopically separated 189, 191, 193Hg. The systematics of the levels are followed from 195Au to 189Au and show a remarkable insensitivity to neutron number. The h 1 1 2 bands are id
