Computer modeling reveals sputtering yields depend on alpha particle energy and incidence angle.
The dependences of the tungsten sputtering yields on the energy of incident alpha particles in the range up to 10 MeV are obtained. 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.
