要旨

We report on improved isotope shift measurements of the isotopes ^40,42,44,48Ca in the 4s²S_1/2→4p²P_3/2 transition using collinear laser spectroscopy. Accurately known isotope shifts in the 4s²S_1/2→4p²P_1/2 (D1) transition were used to calibrate the ion beam energy with an uncertainty of ΔU ≈ ± 0.25 V. The accuracy in the D2 transition was improved by a factor of 5–10. A King-plot analysis of the two transitions revealed that the field shift factor in the D2 line is about 1.8(13)% larger than in the D1 transition which is ascribed to relativistic contributions of the 4p_1/2 wave function.
