Abstract
Measurements of natural radiative lifetimes in atomic tellurium in the 5 p(3)7p configuration are reported. Two-step laser excitation was ap plied on tellurium vapour in a cell that was differentially heated and pumped through a capillary. The decay of the fluorescence signal was recorded at different vapour pressures. The following four radiative l ifetime values were obtained: 7p P-5(1): 128(11) ns, 7p P-5(2): 99(8) ns, 7p P-3(1): 82(10) ns and 7p P-3(2): 124(8) ns.
