We have pointed out that the atomic first ionization energy not only depends on the principal quantum number (n) but also on the azimuthal quantum number (l) of the orbital (n, l) on which the electron of interest is present. The formalism is tested through the calculation of the atomic...
As a disagreement was found by Robinsonbetween measured and calculated values for the ionization potential of Li, I have made a direct calculation by the method described by Hylleraas. The ionization potential in the 13th approximation is found to be 610,058 cm.. This result is in good ...
摘要: The calculation method of total ground state ionization energy is gotten by the improved screened Hydrogenic ionization model. This method is simple and takes into account of relativistic effects. The results are accurate as compared with experiments....
From these data we determine the binding energy of the 2 1S level to 2.2 parts in 1010 by using a Ritz series formula. This high-precision determination of the 2 1S binding energy does not depend on theoretical calculation of the binding energy of any helium level. The result, 32 033.228...
The formula allows to speed up considerably calculations of energy ionization losses fluctuations of a relativistic charged particle in the very thin matter layers. The suggested calculation scheme can be useful for optimization of the track detector characteristics in the modern accelerators and ...

79 with a great success for the K-shell ionization of atomic targets in the range 2 ≤ Z≤ 92 for the incident energy EThreshold≤ E≤ 106 keV. A relatively simple approximate formula, known as KLV model in literature,48 was derived by Kolbenstvedt combining both the distant and close ...
Finally, we define the physics of different mechanisms for radiation loss, as this is always an important factor in plasma energy balance. The calculation of degree of ionization and properties of species undergoing ionization can be difficult in general. The details of the ionization process for ...
1. For comparison, we also show in the Figure the results we obtain for Qn using the SFA (the details of this calculation are given in the Section “Methods”), and the results we obtain using a stochastic model of the ionization process we present below. Figure 1 Distributions of ...
