Abstract:
A complete set of atomic data of CuI, including the energy levels,
oscillator strengths, and photoionization cross sections, is
theoretically studied to investigate element abundance including
nonlocal thermodynamic equilibrium (NLTE) effects. The calculations
are carried out by using the R-matrix method in the LS-coupling
scheme. Twenty terms of CuII are utilized as target states, and
extensive configuration interactions are included to properly
delineate the quantum states of CuII and CuI. One hundred thirteen
bound states and 1699 oscillator strengths for E1 transitions between
these states are obtained. Photoionization cross sections for all
bound states are calculated in a photon energy range covering 1.28Ry
from the threshold of the respective state. Resonances shown in the
photoionization cross sections are identified, and some strong
resonances are expected to play an important role in NLTE modeling.
The atomic data in this work represent the first complete data set for
copper abundance studies. Our results are compared with the
experimental and other theoretical data wherever available.
