Radiative lifetime measurements based on time-resolved laser-induced f
luorescence are reported for 107 odd-parity and 168 even-parity levels
of Dy I and 130-odd parity and 35 even-parity levels of Dy II. The Dy
I levels range in energy from 15 000 to 46 000 cm(-1), and the Dy II
levels range in energy from 20 000 to 50 000 cm(-1) These lifetimes, w
ith a few exceptions, are accurate to +/-5%. (C) 1997 Optical Society
