Dynamics of production of iodine atoms by dissociation of iodides in a pulsed self-sustained discharge

Absorption at the laser transition has been used for the first time to assess the evolution of concentration of iodine atoms in a pulsed self-sustained discharge in mixtures of iodides with a buffer gas such as molecular nitrogen and helium. Dynamics of the iodine atom production is studied by the m...

Description
Summary:Absorption at the laser transition has been used for the first time to assess the evolution of concentration of iodine atoms in a pulsed self-sustained discharge in mixtures of iodides with a buffer gas such as molecular nitrogen and helium. Dynamics of the iodine atom production is studied by the method of absorption spectroscopy. The dissociation of and () iodides is investigated. The energy required to produce atomic iodine is evaluated. The experimental data obtained for are compared with the results of numerical simulations, their reasonable agreement being demonstrated.
