Effect of dust particle size on charged particles collision processes in complex plasma

Collision processes between interacting particles have extensive applications, in particular for studying the transport properties of gases, plasmas and other similar systems [1–4]. The collision processes of charged particles have been investigated on the basis of the modified Yukawa potential considering the particle radius [5]. Collision processes such as scattering, contact collision of charged particles in the field of dust particles taking into account their size have been studied. Plasma charged particle’s trajectories, scattering angles, and the total momentum transfer cross sections in the field of the dust particle at different values of its finite size have been obtained. The impact of dust particle size on both scattering processes and contact collision of charged particles with dust particles has been revealed.
