Based on the minimal length uncertainty, both the spectral lines and natural broadening of spectral lines of hydrogen atom may be corrected in the sub-nano-meter space time. It is interesting to obtain the related spectral line profile of the corrected hydrogen atom spectrum, which is presented ...

The abundance of calcium relative to hydrogen in the solar atmosphere is 8.51×10-6, and it is sufficiently high to allow a large number of strong lines to be emitted by plasmas in the solar atmosphere in the UV, EUV, and X-ray spectral ranges. Such lines allow detailed studies of the...
It is shown that line intensities and main energy level shifts are directly related to the non-spherical and time-dependent electric field of the atomic core. 关键词: Theoretical or Mathematical/ atomic spectra spectral line shift/ spectral lines classical atom line intensities energy level shifts ...
An energy-level diagram for a hydrogen atom and several possible atomic transitions are shown in Figure 2 When we measure the energies involved as the atom jumps between levels, we find that the transitions to or from the ground state, called theLyman seriesof lines, result in the emission ...
spectrum line- an isolated component of a spectrum formed by radiation at a uniform frequency atomic spectrum- (physics) a spectrum of radiation caused by electron transitions within an atom; the series of spectrum lines is characteristic of the element ...

Hydrogen(deuterium) gas discharge source was used to bombard target of non-crystalloid deuterate polyethylene polymethylmethacrylate,etc.The scattering spectrum was measured.There are several sharp X-ray spectral lines on the scattering spectrum,but the primary spectrum of the discharge does not include...
Spectral line width refers to the range of frequencies within which light is emitted or absorbed by atoms. It is characterized by the central frequency, peak intensity, and the full-width at half-maximum (FWHM) of the frequency distribution. The broadening of spectral lines is influenced by nat...
Weak lines of O II, N II, Si II, Si IV, and Mg II define the subclasses B0.5–B9.5. The hydrogen lines and line ratios of Si III, Si IV, and O II to He I all weaken with increasing luminosity. For the A-type stars, characterized by the strongest H I Balmer lines, the Ca ...
