The samples of tungsten with a purity of 99.5 and 99.7% were irradiated with helium ion beams (EHe⁺ = 0.12 MeV). The total sputtering coefficients for the sample depth up to 60 Å from the surface of sample were obtained. It was found that on the surface of tungsten, the number of pits (the flecking...
