New lines in the VUV-emission spectrum of potassium

The potassium emission spectrum in the 50–100 nm wavelength region is investigated utilizing a hollow-cathode discharge of potassium vapor mixture with buffer gas. Three novel lines 77.82 nm, 69.14 nm and 55.45 nm are detected and identified as due to radiative decays of quartet autoionizing levels...

Zusammenfassung:The potassium emission spectrum in the 50–100 nm wavelength region is investigated utilizing a hollow-cathode discharge of potassium vapor mixture with buffer gas. Three novel lines 77.82 nm, 69.14 nm and 55.45 nm are detected and identified as due to radiative decays of quartet autoionizing levels of K I.
