Probabilities of radiative transitions in the spectra of nickel-like ions Cd XXI, In XXII, and Sn XXIII

Probabilities of electric-dipole $3d^{9}4p\to 3d^{10}$, $3d^{9}4s$ transitions in the spectra of nickel-like ions Cd XXI, In XXII, and Sn XXIII are calculated semiempirically in the intermediate coupling scheme. The radial integrals necessary for obtaining absolute values of the probabilities are calculated in the length form with Hartree–Fock functions.
