The L x rays of Ho and Sm produced by proton and /sup 3/He impacts were measured with a Si (Li) detector over the incident energy ranges E/sub p/=0.75-- 4.75 MeV and E3/sub He/=1.5-- 9.3 MeV in the direction of 90/sup 0/ to the projectile. Ratios of x-ray-production cross sections for the L..cap alpha.. and L/sub l/ lines depend markedly on projectile energy but are independent of the projectile charge. It is shown that these experimental results are in good agreement with the plane-wave-Born-approximation calculation taking into account the effect of inner-shell alignment.
