Abstract
Radiative lifetimes and branching ratios of atomic Gd were investigate d by a three-step delayed photoionization method; the lifetimes of 10 even states in the 16000-18500 cm(-1) region and 64 odd states in the 31000-36500 cm(-1) region, and the branching ratios of 19 transitions originating from the f(7)ds(2) D-9(J=2-6)0 ground-state state multiple ts were measured for the first time. By combining these experimental l ifetimes and branching ratios, oscillator strengths were determined an d compared with previously reported values.
