Processes of emission of the molecular and atomic spectra of nitrogen observed in the light of the polar auroraNew experiments have been performed on the discharge and afterglow spectrum of a nitrogen-helium mixture. Their spectral composition is very different: The apparent excitation of this ...
B Weiland,J Hüttermann - 《International Journal of Radiation Biology & Related Studies in Physics Chemistry & Medicine》 被引量: 101发表: 1999年 Ultraviolet Emission Spectrum of Electron-Bombarded Superfluid Helium The emission spectrum of electron-bombarded superfluid helium has been measured as a ...
An inductively coupled plasma is the stable plasma created using radio frequency coupling coiled around an argon or helium “torch”. This plasma is highly energized, the equivalent of approximately 8000K, which rapidly atomizes and iodizes all elements introduced to it, which can then b...

(heliumandlithium, respectively). To the extent that the Schrödinger equation can be solved for more-complex cases, atomic theory is capable of predicting from first principles the properties of all atoms and their interactions. The recent availability of high-speedsupercomputersto solve the ...
About 0.2% to 0.4% of fissions areternary fissions, producing a third light nucleus such ashelium-4(90%) ortritium(7%). The fission products themselves are usually unstable and therefore radioactive. Due to being relatively neutron-rich for their atomic number, many of them quickly undergobet...
… though most of the schemes proposed thus far require completely new technology like helium-cooled high-temperature reactors How is that “completely new”? We had such reactors operating commercially in the US and in Germany back in the 1980’s. This is “back to the future” technolo...
For example, the role of hyperfine-induced multiple interference on the anisotropic character of the angular distribution of the magnetic-quadrupole line of helium-like thallium ions following the electron-impact-induced excitation [11]. Moreover, the process of dielectronic recombination (DR) in ...
2 He High Flow – For certain element groupings, additional helium carrier makeup gas flow is added. 3 Performance for elements offered in multiple groups may vary depending on the reagent gas(es) used. 3 G2350A AED Signal Processing Safety Certifications Characteristics Raw data consists of ...
