Abstract

X-ray spectra emitted by a laser produced plasma are analyzed using calculated X-ray energies for Co-, Ni-, Cu-, Zn-, Ga-, Ge-, As-, Se-, Br-, Kr-, Rb-, Sr-, Y-, and Zr-like lead ions. The charge state distribution in the plasma is studied and a functional dependence of this distribution as a function of the ionic charge, atomic number, free electron density and temperature in the plasma is proposed.
