The first direct radiative lifetime measurements in W I are described. Radiative lifetimes of 15 levels from the 5d46s(a6D)6p(z7D0), 5d46s(a6D)6p(z5F0), 5d5(a6S)6p(z7P0),, and 5d46s(a6D)6p(z5P0)
terms are reported with an accuracy of ±5%. The lifetimes are measured
using time-resolved laser-induced fluorescence and a novel atomic-beam
source. This novel hollow cathode effusive beam source produces an
intense beam of ground-state W atoms and metastable W atoms.
