Measurement of Doppler-shifb profile of yttrium atomic beam was performed by using a tunable dye laser and laser induced fluorescence (LIF) technique. Comparing the intensities of two LIF which originate from the ground state and metastable state with different velocity, the lifetime of the metastable statc a2D5/2 of yttrium was measured to be (0.8+0.2)ms.

The atomic-beam velocity distribution of Gd atomic metastable levels, 215 cm −1 , 533 cm −1 were measured by means of the laser induced fluorescence method. Their lifetimes are deduced from the change of the velocity distributions at two different probe areas along the beam axis. The experimental results show that this is a very simple, sensitive and effective method to measure the lifetime of atomic metastable level

The atomic beam velocity distribution of Gd atomic metastable levels, 215cm-1 533 cm-1 and 999 cm-1 were measured by means of laser induced fluorescence method. Their lifetimes are deduced from the change of the velocity distributions at two different probe areas along the beam axis. The experimental results show that this is a very simple, sensitive and effective method to measure the lifetime of atomic metastable level.
