Abstract

Many-body perturbation theory is implemented to calculate the isotope shifts of 4s, 4p1/2, 4p3/2, 3d3/2, and 3d5/2 energy levels of Ca+ for even isotopes A=40, 42, 44, 46, 48. The results are presented for mass shift and field shift, as well as for higher-order field shifts, quadratic mass shift, nuclear polarization correction, and the cross term between field and mass shifts. Additionally, we examine King-plot nonlinearities introduced by higher-order isotope-shift corrections to the combinations of 3d3/2→4s, 3d5/2→4s, and 4p1/2→4s transitions. For these transitions, second-order mass shift and nuclear polarization correction are identified as the dominant sources of King-plot nonlinearity.
