Resumo

An ordered structure of macroscopic particles has been experimentally observed in a classical neutral thermal plasma using a laser time-of-flight system. The strongly coupled thermal plasma consists of Ce02 particles and electrons emitted by the latter under atmospheric pressure and temperature of 1700 K. The particles are charged positively and suspended in a plasma flow. Their charge is about 103e and the calculated value of a Coulomb coupling parameter γp is >120 that corresponds to a strongly coupled plasma.
