A vacuum sliding spark for the excitation of an intense lithium III spectrum
A sliding spark with a total inductance of 20 nH has been developed. The Li electrodes have been separated by a polythene insulator containing a Li-disk. A ta voltage of 10 kV the Lyman lines and continuum of Li III have been produced. Also the most intensive spectral line of the Paschen series coul...

A sliding spark with a total inductance of 20 nH has been developed. The Li electrodes have been separated by a polythene insulator containing a Li-disk. A ta voltage of 10 kV the Lyman lines and continuum of Li III have been produced. Also the most intensive spectral line of the Paschen series could be observed. The electron density n$_{e}$ has been determined by the formula of Inglis and Teller to be N$_{e}$ = $10^{18}cm^{-3}$, the electron temperature T$_{e}$ from the decreaseof the Lyman continuum of Li III to be T$_{e}$ = 20 ev. Comparing spectral lines from Lyman and Paschen series coming from transitions with the same upper level it seems to be possible to make relative and absolute intensity measurements in the short wavelength UV (100 $\mathring{A}$). |
