We have calculated 87 fine-structure energy levels of K 7+ and Ti 10+ belonging to the lowest 14 configurations within the n=3 and n=4 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.
