Emission spectrum helium

WebIons with multiple inner-shell vacancies frequently arise due to their interaction with different targets, such as (intense) light pulses, atoms, clusters or bulk material. They are formed, in addition, if highly charged ions approach surfaces and capture electrons at rather large distances. To explore the interaction of such hollow ions and their subsequent relaxation, … WebThe emission spectrum obtained in the wavelength range of 200-900 nm for atmospheric helium plasma at 1.5, 2.5 and 3.5 kW are shown in Fig. 2.
