  Rates and line strengths are calculated for the 2s22p53l3l' - 2s22p63l'' and
2s2p63l3l' - 2s22p63l'' electric-dipole (E1) transitions in Na-like ions with
nuclear charges ranging from Z = 14 to 100. Relativistic many-body perturbation
theory (RMBPT), including the Breit interaction, is used to evaluate retarded
E1 matrix elements in length and velocity forms. The calculations start from a
1s22s22p6 Dirac-Fock potential. First-order RMBPT is used to obtain
intermediate coupling coefficients and second-order RMBPT is used to calculate
transition matrix elements. A detailed discussion of the various contributions
to dipole matrix elements is given for sodiumlike copper (Z = 29). Transition
energies used in the calculation of transition rates are from second-order
RMBPT. Trends of transition rates as functions of Z are shown graphically for
selected transitions.
