Abstract
The propagation of the dust electro-acoustic (DEA) mode in dusty plasma wit h different electron and ion temperatures T-e and T-i and different ion spe cies is studied. The critical ratio of the dust space charge to the ion spa ce charge epsilon for the excitation of DEA mode is found to decrease with increasing T-e/T-i and increase with m(i)/m(e) (m(i) and m(e) are the ion a nd electron masses). Thus experiments with hydrogen plasma where electrons are sufficiently hotter than ions and where the reduction in the dust charg e with epsilon is more than 50% are essential for the observation of self-s hielding and the DEA mode.
