Abstract

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.

Keywords
