Abstract

A charge-exchange cell based on pulsed-laser ablation has been developed and applied to collinear resonance ionization spectroscopy. A fast lithium ion beam has been neutralized in the charge-exchange cell and resonance ionization spectra of the 2s2S1/2−2p2P1/2,3/20 transitions of lithium have been successfully observed. The charge-exchange efficiency of the cell is discussed.

Abstract

The lithium ion beam was neutralized in a newly developed charge-exchange cell. The charge exchange was performed with sodium, lithium and iron vapors. The lithium atom was photoionized in a three-step resonance-ionization scheme where the first-step excitation was performed with a cw external-cavity diode laser. The resonance ionization with a diode laser and a pulsed dye laser was as efficient as that with two high-power pulsed dye lasers.
