ACCURATE F VALUES OF ASTROPHYSICAL INTEREST FOR NEUTRAL CARBON

A new set of accurate transition probabilities based on configuration interaction wavefunctions has been obtained for many transitions of as trophysical interest in the singlet and in the triplet systems and for intercombination lines of C I. The CIV3 code of Hibbert was used for the calculations and small empirical adjustments were introduced to th e diagonal matrix elements in order to reproduce accurately the observ ed energy splittings between the energy states. The accuracy of the re sults has been tested from comparisons with the experimental and theor etical results previously available.
