Radiative lifetimes measured with time-resolved laser-induced fluorescence
are reported for 39 odd-parity levels and 42 even-parity levels of Ho I and
37 even-parity levels of HoII. The levels of Ho I range in energy from 17
000 to 41 000 cm(-1), and those of Ho II from 20 000 to 38 000 cm(-1) These
lifetimes, with some exceptions, are accurate to +/-5%. (C) 1999 Optical S
