Abstract: The isotope shifts (IS) of the resonance lines 4sS-2(1/2)-4p2P(J) in CaII (seven isotopes) have been measured by fast ion beam collinear laser spectroscopy (FIBCLS) with non-optical detection of the resonant laser-ion interaction. The electronic field shift factor F was derived from the experimental IS via a King plot procedure using the mean square nuclear charge radii from muon spectroscopy and electron scattering. The J-independent result F = -283(6) Mhz/fm2 was obtained. The F-value resulting from extensive many body perturbation theory (MBPT) calculations, recently performed by Martensson-Pendrill et al., is in excellent agreement with the experimental value, confirming the reliability of the MBPT procedure.
