Abstract
An experiment on ion-acoustic solitary waves in dusty plasma is performed i n a dusty double-plasma device. The leading part of a sinusoidal pulse deve lops to an oscillation. The troughs of the oscillation become shallow when dust particles are mixed into the plasma. The Mach velocity of the first pe ak in the oscillation decreases due to the presence of negatively charged d ust grains for a fixed height of the peak. The width of the peak normalized with Debye length increases when the dust particles are introduced into th e plasma. The experimental results are compared with the numerical integrat ions of a modified Korteweg-de Vries-Burgers equation which contains the te rms of kinematic viscosity and of collisions of ions with the dust particle s.
