Abstract:
The main goal of this paper is to present accurate and extensive
transition data for the PII ion. These data are useful in various
astrophysical applications.
The multiconfiguration Dirac-Hartree-Fock (MCDHF) and relativistic
configuration interaction (RCI) methods, which are implemented in the
general-purpose relativistic atomic structure package GRASP2K, were
used in the present work. In the RCI calculations the
transverse-photon (Breit) interaction, the vacuum polarization, and
the self-energy corrections were included.
Energy spectra are presented for 48 even states of the 3s23p2,
3s23p{4p, 4f, 5p, 5f, 6p}, 3s3p23d configurations, and for
58 odd states of the 3s3p3,
3s23p{3d, 4s, 4d, 5s, 5d, 6s} configurations in the PII
ion. Electric dipole (E1) transition data are computed between these
states along with the corresponding lifetimes. The average uncertainty
of the computed transition energies is between five and ten times
smaller than the uncertainties from previous calculations. The
computed lifetimes for the 3s23p4s3Po states are within the
error bars of the most current experimental values.
Description:
Table 5 presents electric dipole (E1) transition data between the
states of the calculated energy levels for the PII ion. In the Table
transition data as wavelengths, weighted oscillator strengths,
transition rates of E1 transitions and the accuracy indicator dT are
given. The results in Table 5 is ordered by wavelength (the 8 column).
Transition data are given with A>1000s-1.
