Isotope Structure and Hyperfine Splitting of 326.1 nm 113Cd line

In the course of this work the influence of the isotope structure of the 326.1 nm (51S0-53P1) cadmium line on the resulting line shape was carefully studied. Measurements for the 113Cd line perturbed by Ne at low pressure (below 2 Torr) were used for determination of isotope shifts of cadmium hyperfine components. The results has been used as a starting point for the analysis of more than 90 spectra of the line under investigation perturbed by different gasses in wide pressure range. That allowed us to determine the hyperfine splitting for 113Cd 326.1 nm line with uncertainty below 10-3 cm-1.
