Abstract

Relative metastable level population of metal plasma having low-lying metastable states departs from equi-librium value. It needs to be experimentally investigated. This paper reports the use of hollow cathode lamp based Laser Induced Fluorescence (LIF) spectroscopy technique to measure Relative metastable level popu-lation of metal in a plasma produced by a hollow cathode lamp. The relative population of ground state and 533 cm-1 levels of Gd atoms in hollow cathode lamp is measured with LIF method.
