The charge exchange process in collisions of H+ with Li 5d is investigated using the two-center atomic-orbital close-coupling method. The state-selective cross-sections are obtained in the energy range of 0.5—10 keV. It is found that the processes for capture to n=4—7 are the dominant reactionsand the n-distribution of state-selective cross-sections is weakly dependent on the collision energy. But the l-distribution of state-selective cross-sections strongly depends on the collision energy. For the lower collision energy around 1 keVthe l-distribution increases with increasing l. Howeverthe l-distribution moves to the lower quantum number as the collision energy increasesand the maximum value appears around l=1.
