New exsperiments on gas target spectroscopy. Atomic life-time measurements of some deuterium levels

Abstract

The impact of heavy ions on various gaseous targets was observed within the energy range available in the Institute of Nuclear Physics, Cracow 200 keV accelerator. The ions passing through a gas target were recharged and excited. The spontaneous deexcitation radiation was measured. New transitions in ionic species were observed and the time of flight method of life-time measurements applied. The results of the experiments on the deuterium spectrum are discussed. Measurements of life-times of upper levels of the corresponding transitions are described in detail on the D[α] λ = 656 nm /п=3/ and D[γ] λ = 434 nm lines.
