... The emission spectra of He consists of a number of series in the visible region of the spectrum as well as in the near & far UV regions. There are twice as many line series as for the alkalis; two principal series in the visible and near UV, as well as two diffuse, two sharp and two fundamental seri ...

Semiclassical calculation of electron spectra in atoms through two
... confirmed the dependence even for not small orbital momentum l 1, 2, 3 . That was a basis of the proposed method to calculate the electron spectra in atoms. The semiclassical approach is applied to calculate one-electron spectrum in a free atom. The atomic number scaling in the Thomas-Fermi model ...

Nuclear Forces and Mesons
... Since nuclei are composed of nucleons (protons and neutrons), we want information on the nucleon-nucleon (NN) potential. Two ways to study this: scattering experiments (free nucleons) or bound states (nuclei). This is analogous to studying the Coulomb force between an electron and a nucleus: you ca ...
