Hartree-Fock Calculations of Coronal Forbidden Lines in the Argon i Iso-Electronic Sequence
Abstract
In the Argon i isoelectronic sequence it is highly likely that coronal forbidden visible transitions will be discovered occurring between levels of the lowest excited configuration 3p53d. Hartree-Fock calcula- tions of wavelengths and magnetic dipole and electric quadrupole transition probabilities have been made in the ions Cr vii to Cu xii. In these stages thirty-four forbidden lines are predicted having transition probabilities greater than 1 sec'. Due to large uncertainties inherent in state-of-the-art self-consistent field calculations, the predicted wavelengths have insufficient accuracy at present to allow a unique identification with coronal lines observed at eclipses
