Singly and doubly ionized carbon  Structure and transition probabilities
Abstract
Radial functions calculated at a central potential are used to study the validity of atomic structure and transition probability calculations for ionized carbon. Experimental beam foil measurements and theoretical data are compared. It is suggested that the calculation of satisfactory eigenfunctions is improved by replacing the oneconfiguration approximation and instead using a broader expansion expressed in terms of different oneelectron angular functions; the HartreeFock selfconsistent field calculation is not required. A procedure used to consider the influence of direct and indirect cascades on the observed lifetime of a particular state is noted. For doubly excited states in C(+) the relative probabilities for radiative decay or autoionization are calculated. Astrophysically important transition probabilities for 10 members of the Be I sequence are calculated.
