A new version of the program FITTER for fitting atomic hyperfine structure in optical spectra including the calculation of confidence intervals

Andreas Zeiser et al.

Summary: This paper introduces an extended version of the FITTER program, which can now calculate confidence intervals for adjusted parameters when analyzing hyperfine structure. The addition of confidence intervals provides essential information to the results. The application is discussed using an example.

Experimental investigation of the hyperfine structure of Tm I with Fourier transform spectroscopy part b: In the NIR wavelength range from 700 nm to 2250 nm

Taha Yusuf Kebapci et al.

Summary: In this study, the hyperfine structure of 43 spectral lines of atomic thulium was investigated. Experimental determination of the magnetic-dipole hyperfine constant A was conducted for 17 fine structure levels, with 14 of them being determined for the first time.
