Abstract

The dependence of the Ar+ metastable density nd(3d4F7/2) on the electron density ne and its radial profile were studied in the range ne=1014∼1015 cm-3 by using the LIF method in an Ar pulsed-discharge plasma. The measured LIF intensity was strongly affected by electron collisional quenching. The corrected LIF intensity was proportional to both the n(3d4F7/2) estimated by a C–R model and the measured ne. Its radial profile agrees fairly well with the ne measured by a double-probe.
