Quadrupole interactions in the hyperfine structure of the titanium atom

Analysis of the hyperfine structure experimental data for the even configuration system in the titanium atom allow to divide the observed hyperfine splittings into contributions of ranks K=1,2 and 3 of the hyperfine structure operator. The direct diagonalization of the hyperfine structure matrix yield the corrected values of the hyperfine structure constants A, B and C. The observed and calculated hyperfine structure intervals were in good agreement within the experimental accuracy. Using the fine structure eigenvectors and the quadrupole interactions angular coefficients matrix, the radial parameters of the magnetic quadrupole interactions were determined.
