The parameters of scattering (reflection) of charged particles by the leading edge of a dust acoustic
soliton are analyzed. The soliton profile is calculated using the Sagdeev pseudopotential approach.
To analyze the motion of charged particles, the Newton’s second law is used. It is shown
theoretically that the charged particle scattering can be elastic and inelastic. The nature of
scattering significantly depends on the presence of dissipation. In the dissipative case, charged
particles scattering is the process of an oscillatory nature. It is shown that it can be considered as a
new type of oscillations of charged particles in plasma. The parameters of the oscillations are
calculated both numerically (nonlinear case) and analytically (within the linear approximation).
Theoretical results are compared with known experimental results, as well as the applied aspect is
stated.
