Using techniques similar to those previously employed, we apply the eikonal approximation to the evaluation of the cross section for electron capture from an arbitrary nlm shell of a hydrogenic target atom into an arbitrary n'l'm' of a fast hydrogenic projectile. The results are obtained in exact analytical closed form. Numerical results are presented for the case H/sup +/+H(1s)..-->..H(n'l'm')+H/sup +/ when n' = 2 and 3. Comparison is made with the corresponding Oppenheimer-Brinkman-Kramers Oppenheimer-Brinkman-Kramers (OBK) results.
