摘要：

The lifetime of the metastable P-3(2) state of neon has been determined as 14.73(14) s [decay rate 0.067 90(64) s(-1)] by measuring the decay in fluorescence of an ensemble of Ne-20 atoms trapped in a magneto-optical trap (MOT). Due to low background gas pressure (p<5x10(-11) mbar) and low relative excitation to the D-3(3) state (0.5 % excitation probability) only small corrections have to be included in the lifetime extrapolation. Together with a careful analysis of residual loss mechanisms in the MOT a lifetime determination to high precision is achieved.
