New radiative lifetime measurements based on time-resolved laser-induced fluorescence
techniques are reported for 18 even-parity levels belonging to the 
and 
configurations of Ce I and 6 even-parity levels belonging to the 
, 4f5d6p, and 4f6s6p
configurations of Ce II. Free neutral and singly ionized cerium atoms were produced by laser
ablation. The Ce I and Ce II levels range in energy from 26 545 to 29 102 cm-1, and 42 573 to
48 152 cm-1, respectively.
