Radiative lifetimes of the energy levels of palladium-like ions Pr XIV and Nd XV

Radiative lifetimes for the $4d^{9}4f$, $4d^{9}5p$, $4d^{9}5d$, and $4d^{9}6s$ levels in the spectra of palladium-like ions Pr XIV and Nd XV are calculated in the electric-dipole approximation by the intermediate coupling semiempirical method with the use of experimental energy levels available in the literature. The radial integrals of transitions necessary for calculating absolute values of transition probabilities are obtained in the length form with Hartree–Fock functions.
