Abstract
Ordered structures formed of 300-mu m-long cylindrical nylon grains with di ameters of 15 and 7.5 mu m are obtained. In contrast to conventional spheri cal monodisperse grains, which, under certain conditions, form the plasma-d ust Coulomb crystal, the cylindrical grains in the plasma acquire a charge of similar to 7 x 10(5) electrons and form a structure similar to a liquid crystal. The parameter characterizing the nonideality of the dusty componen t of the plasma attains 10(6). Grains are suspended in the striation in the horizontal plane and line up in parallel with each other. (C) 2000 MAIK "N auka/Interperiodica".
