It was found that some of sputtered particles identified as H, H₂ and OH by the quadropule mass spectrometer (QMS) as well as their corresponding optical spectra of H, H₂ and OH are detected too.

In this report also presents that the radiation intensity was measured as a function of beam energy and the angle of incidence.
