  Energies of (3s2 3p6 3d9 4l4l'), (3s2 3p5 3d10 4l4l'), and (3s 3p6 3d10
4l4l') states for Cu-like ions with Z = 30 -100 are evaluated to second order
in relativistic many-body perturbation theory (RMBPT) starting from a Ni-like
Dirac-Fock potential. Second-order Coulomb and Breit-Coulomb interactions are
included. Correction for the frequency-dependence of the Breit interaction is
taken into account in lowest order. The Lamb shift correction to energies is
also included in lowest order. Intrinsic particle-particle-hole contributions
to energies are found to be 20-30% of the sum of one- and two-body
contributions. Transition rates and line strengths are calculated for the
3l-4l' electric-dipole (E1) transitions in Cu-like ions with nuclear charge Z =
30 - 100. RMBPT including the Breit interaction is used to evaluate retarded E1
matrix elements in length and velocity forms. 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 the dipole matrix elements and energy levels is given for
copperlike tungsten (Z = 74). The transition energies used in the calculation
of oscillator strengths and transition rates are from second-order RMBPT.
Trends of the transition rates as functions of $Z$ are illustrated graphically
for selected transitions. Comparisons are made with available experimental
data. These atomic data are important in modeling of M-shell radiation spectra
of heavy ions generated in electron beam ion trap experiments and in M-shell
diagnostics of plasmas.
