摘要：

The lifetimes of the 4s 4p P-3(1) and 4s 3d 1D2 metastable states of Ca have been studied using the time-of-flight technique. Two kinds of observations were performed. First, the exponential decay of the fluorescence, using a (continuous) dc discharge for excitation and then the velocity distribution of the radiating atoms, using a pulsed discharge, were measured. From the combined results of these measurements the lifetimes were derived. The lifetimes of the 4s 4p P-3(1) and 4s 3d 1D2 states of Ca are determined to be 0.57 +/- 0.03 ms and 1.5 +/- 0.4 ms, respectively.
