A formula is proposed that describes the behavior of the sputtering yield at energies above 100 keV. The results are obtained by computer modeling using multiparameter potentials. For thermonuclear alpha particles with an energy of 3.5 MeV, the dependence of the sputtering yield on the angle of incidence of the beam on the target is obtained.</p></abstract><trans-abstract xml:lang="ru"><p>Получены зависимости коэффициентов распыления вольфрама от энергии падающих альфа-частиц в диапазоне до энергий 10 МэВ.
