    "abstract": "Rates and line strengths are calculated for the 2s22p53l3l\u0027 - 2s22p63l\u0027\u0027 and\n2s2p63l3l\u0027 - 2s22p63l\u0027\u0027 electric-dipole (E1) transitions in Na-like ions with\nnuclear charges ranging from Z = 14 to 100. Relativistic many-body perturbation\ntheory (RMBPT), including the Breit interaction, is used to evaluate retarded\nE1 matrix elements in length and velocity forms. The calculations start from a\n1s22s22p6 Dirac-Fock potential. First-order RMBPT is used to obtain\nintermediate coupling coefficients and second-order RMBPT is used to calculate\ntransition matrix elements. A detailed discussion of the various contributions\nto dipole matrix elements is given for sodiumlike copper (Z = 29). Transition\nenergies used in the calculation of transition rates are from second-order\nRMBPT. Trends of transition rates as functions of Z are shown graphically for\nselected transitions.",
