Dynamics of the emission spectrum of the hydrogenoxygen plasma of pulsed discharge in water in the range of the Balmer series with a minimum of impurities
The results of experimental investigations of the spectral distribution of radiation of hydrogen - oxygen plasma pulsed discharges in water in a minimum difference of radiation from the blackbody radiation (BBR) are given. The pressure in the plasma channel was changed from 5000 to 80 atm, the brigh...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The results of experimental investigations of the spectral distribution of radiation of hydrogen - oxygen plasma pulsed discharges in water in a minimum difference of radiation from the blackbody radiation (BBR) are given. The pressure in the plasma channel was changed from 5000 to 80 atm, the brightness temperature of 24·10³ to 7·10³ K. The difference in brightness temperatures of the violet and the red area does not exceed ± 2000 K of the average temperature. With the relaxation of plasma electron density decreased from 2·10²⁰ to 10¹⁷ cm⁻³. It is shown that at high concentrations of electron spectral distribution of the radiation in the spectral range of the Balmer series differs little from the blackbody radiation is not observed and none of the hydrogen Balmer line. This indicates "non-realization" even the top level line Hα. (656.2 nm, with excitation energy of the upper level of 12.09 eV). As the relaxation of the plasma to be consistent line Нα, Нβ, Нγ. There is a redistribution of the broadening of the hydrogen lines of the Bal-mer series. At Ne ≤ 10¹⁷ сm⁻³ hydrogen emission spectrum coincides with the traditional. |
