Advances in Studies of Physical Processes
Abstract
Advances in calculations of physical processes in planetary nebulae have been attained with regard to (1) excitation of forbidden lines, (2) transition probabilities np3 2D5/2 to 4S, 2D3/2 to 4S; (3) hydrogenic recombination spectra; and (4) permitted lines other than those of H I, He I and He II. Problems in these calculations are mentioned, and accuracies are judged.
