A parametric analysis of the fine and the hyperfine structure
for the three even configurations 
, 
and 
has been performed.
Effective one-electron parameters 
, 12 and 10)
and 
were determined for these three configurations.
Extremely large ratios 
were found.
Theoretical predictions for the hyperfine structure constants A and B
for all levels of the configurations , and
have been determined from experimental data.
Additionally, the fine and hyperfine structure for the
two energetically high lying even configurations 
and 
are discussed.
The results presented here call into doubt the existence
of the fine structure levels 
at an energy of 39 408.88 cm-1
and 
at 18 876.46 cm-1
given in the Moore tables.
