We have calculated 87 fine-structure energy levels of
K7+ and Ti10+ belonging to the lowest 14 configurations
within the 
and 
complexes using Program CIV3 of Hibbert.
Relativistic effects are included through the Breit-Pauli approximation.
New improved results of oscillator strengths, transition probabilities
and line strengths for all allowed and intercombination transitions
among these fine-structure levels are calculated using large-scale
configuration interaction wavefunctions. Lifetimes of some relatively
longer-lived levels are also computed. Our results are compared with
a wide variety of other calculations and available experimental data.
It is noted that most of our results compare more favourably with the
measurements than the other available theoretical results.
