The appearance of third charged particles groups has fixed, when the laser radiation interact-ed with metal target in rarefied environ gas. The intensity of optical range laser radiation was  109 W/cm2. The opportunity of using Langmuir probe for diagnosing plasma processes with nanosecond resolution has demonstrated

Experimental studies of aerosol nucleation in air, containing trace amounts of ozone, sulphur dioxide and water vapour at concentrations relevant for the Earth's atmosphere, are reported. The production of new aerosol particles is found to be proportional to the negative ion density and yields nucleation rates of the order of 0.1–1 cm −3  s −1 . This suggests that the ions are active in generating an atmospheric reservoir of small thermodynamically stable clusters, which are important for nucleation processes in the atmosphere and ultimately for cloud formation.
