%X Rutherford backscattering spectrum of protons in H+ 2,H+ 3 cluster ions have been measured in channeling directions <100> and <110> of silicon crystal. It has been found that, under the same velocity of 650 keV/p, the backscattering probability for protons of H+ 2 cluster ions is greater than that of H+ projectile, and the backscattering probability for protons of H+ 3 is greater than that of H+ 2. The ratio of backscattering yields of channeling direction to that of random direction is defined and the depth dependence of ratio distribution is calculated.
