description

© 2019 The Authors Calculations of the neutralisation cross-section and relative population of atomic states were performed for ions beams (1 ≤ Z ≤ 89) at 5 and 40 keV incident on free sodium and potassium atoms. To test the validity of the calculations, the population distribution of indium ions incident on a vapour of sodium was measured at an intermediate energy of 20 keV. The relative populations of the 5s 2 5p 2 P 1/2 and 5s 2 5p 2 P 3/2 states in indium were measured using collinear resonance ionization spectroscopy and found to be consistent with the calculations. Charge exchange contributions to high-resolution lineshapes were also investigated and found to be reproduced by the calculations. The reliable prediction of relative populations and reproduction of lineshapes are of importance to high-precision and efficient laser spectroscopy studies of exotic isotopes and future applications of collinear resonance ionization spectroscopy. ispartof: SPECTROCHIMICA ACTA PART B-ATOMIC SPECTROSCOPY vol:153 pages:61-83 status: published
