Abstract:
The authors calculated atomic partition functions (APF) for nickel
ions, Ni I - Ni X, using recent compilations of atomic energy levels.
Observed sets of atomic energy levels were filled through levels
predicted in quantum mechanics and autoionization levels. Therefore,
our APFs include levels above those tabulated. APFs are functions of
temperature T and the lowering of ionisation energy (LIE). LIE is the
result of emitter-plasma interactions in gas that cause dissolution of
the highest energy levels and is applied here in a cut-off
approximation.
Description:
APFs are collected in 10 tables, each table for a single ion NiI,
NiII, ..., NiX. Values of APFs (decimal logarithms) are given in a
wide range of temperatures, 103-106K, and lowering of the
ionisation energy, 0.001eV<LIE<5.0eV.
