Abstract:
Complete data sets of level energies, transition wavelengths,
A-values, radiative and Auger widths and fluorescence yields for
K-vacancy levels of the F, Na, P, Cl, K, Sc, Ti, V, Cr, Mn, Co, Cu and
Zn isonuclear sequences have been computed by a Hartree-Fock method
that includes relativistic corrections as implemented in Cowan's
atomic structure computer suite. The atomic parameters for more than 3
million fine- structure K lines have been determined. Ions with
electron number N>9 are treated for the first time, and detailed
comparisons with available measurements and theoretical data for ions
with N=<9 are carried out in order to estimate reliable accuracy
ratings.
Description:
Computed level energies, wavelengths, radiative transition
probabilities, absorption oscillator strengths, radiative and Auger
widths, and K-shell fluorescence yields in ions belonging to the F,
Na, P, Cl, K, Sc, Ti, V, Cr, Mn, Co, Cu and Zn isonuclear sequences
are given in these two tables. In Table 9 levels are identified by the
atomic number (Z), the electron number (N), the level index, the spin
multiplicity, the total orbital angular momentum quantum number, the
total angular momentum quantum number and the electronic
configuration. For each level, the computed HFR energy and its
radiative width are listed. For K-vacancy levels, the Auger width and
the K-shell fluorescence yield are also given. In Table 10 transitions
are identified with the atomic number, the electron number, the upper
and lower level indices tabulating its computed wavelength, radiative
transition probability, weighted oscillator strength, and cancellation
factor.
