A study has been made of the decay of a hydrogen plasma of ion density ~3���1015 cm?3 and temperature ~104�K. Details are presented of the experimental methods used to determine density and temperature distributions in the decaying plasma. The plasma decays by three-body recombination mainly and the experimental values of the recombination coefficient agree with those expected for a plasma opaque to Lyman radiation.

Rates of ion neutralization have been measured in hydrogen chloride, hydrogen bromide, and nitrous oxide by collecting the ions remaining in a defined volume at various times after ionization by a pulse of 120 k.v.p. X-rays. Values of the total homogeneous ion-ion recombination coefficient, a, have been obtained for each gas over a range of pressures in the region 50 to 650 Torr. From a study of the effects of pressure and ion density, the relative rates of wall diffusion, mutual neutralization, and three-body neutralization have been deduced.

Body Recombination

Spectral dynamics of femtosecond laser plasma induced on the sea water surface is investigated. Characteristic decay time of continuum and line intensity of Mg II, Ca II and Na I are determined. Electron density that changes from 3.0·1016to 2.4·1015cm-3was provided by usage of three-body recombination coefficient. It is shown that Na detection limit will be least in comparison with Mg and Ca.

The Mathematical Model

The European laws and recently the Romanian ones impose more and more strict norms to the large nitrogen dioxide polluters. They are obligated to continuously improve the installations and products so that they limit and reduce the nitrogen dioxide pollution, because it has negative effects on the human health and environment. In this paper are presented these researches made within a case study for the Timi�oara municipality, regarding the modeling and simulation of the nitrogen dioxide dispersion phenomenon coming from various sources in atmosphere with the help of analytical-experimental methods. The mathematical model resulting from these researches is accurately enough to describe the real situation. This was confirmed by comparing the results obtained based on the model with real experimental values.
