Measurement of Gd atom metastable levels by laser induced fluorescence spectroscopy
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.
