Critical analysis of the methods of interpretation in the hyperfine structure of free atoms and ions. Case of the even configuration system of the titanium atom — •Jerzy Dembczyński, Magdalena Elantkowska, and Jarosław Ruczkowski — Chair of Quantum Engineering and Metrology, Faculty of Technical Physics, Poznan University of Technology, Nieszawska 13B, 60-965 Poznan, Poland

On the basis of experimental data, the even configuration system in the titanium atom was analyzed. Our investigations indicate that the operator

H_hfs=

∑

K=1

T_e^(κ k)K · T_n^(K)

describes the partition of the observed hyperfine splittings into the contributions of ranks K=1,2 and 3 within the experimental accuracy, while the operator

T_e^(κ k)1 · T_n⁽¹⁾ =
