Abstract:
Breit-Pauli results for energy levels, lifetimes, and Lande g_J_
factors have been determined for all levels up to 2p^2^ 3d of the
nitrogen-like sequence (Z=7-17) and 2p^3^ 3d of the oxygen-like
sequence (Z=8-20). Exceptions are some lower members of the sequence
where the spectrum included only those levels below the second
2p^2^ 4s term in the case of N-like or 2p^3^ 4s in the case of O-like.
The computed energy and E1, E2, M1, M2 transition data between all
levels, including convergence of the LS line strength for both length
and velocity forms, may be viewed at a website,
http://www.vuse.vanderbilt.edu/~cff/mchf_collection .
In this paper, critically evaluated transition data is presented for N
I, O II, Mg VI, and Si VIII (N-like sequence) and O I, Ne III, Mg V,
and Si VII (O-like) for E1 transitions including uncertainty
estimates. Tables 4 and 5 include the computed energy adjusted
transition rates and uncertainty estimates as absolute values are
calculated based on errors from energy adjustment and from LS
convergence. The accuracy of energy levels is determined by comparison
with experiment. Transition rates with uncertainties are compared with
experiment and other theory.

Global notes:
Note (G1): Note to Transition rates:
Transition rates are energy adjusted
NOte (G2): Note to Uncertainties:
Uncertainties are expressed as absolute values and are calculated
based on errors after energy adjustment. Transitions that have not
been adjusted (because of missing observed energies) have no
uncertainty values and are not adjusted for energy errors.
