J-DEPENDENCES OF THE ISOTOPE SHIFTS IN TI-I 3D(2)4S(2) A P-3 AND 3D(3)4P Y D-3(DEGREES) TERMS

Atomic beam laser spectroscopy was used to measure the isotope shifts (IS) and hyperfine structures of all stable titanium isotopes in eight Ti I spectral lines. Six of the lines investigated cover all allowed transitions between the lower 3d(2)4s(2)a P-3 and the upper 3d(3)4p y D-3 degrees terms; two of them are between the 3d(2)4s(2) a P-3(1.2) and 3d(2)4s4p z P-3(2) degrees levels. J-dependences of the rs in the a P-3 and y D-3 degrees terms were established. The contributions of the field and mass shifts to the J-dependence were separated using model-independent data on muonic atom Is and electronic scattering experiments. Evidence for mass shift domination of the J-dependence was provided.
