We re-examine the justification for the imposition of regular boundary conditions on the wavefunction at the Coulomb singularity in the treatment of the hydrogen atom in non-relativistic quantum mechanics. We show that the issue of the correct boundary conditions is not independent of the physical ...
By using the Mathematica and perturbation theory,the energy level splitting(n=2-7)for the hydrogen atom in a stronger magnetic field is computed.The applicable condition of perturbation method is discussed.The numerical results show that:In general,the degeneracy of energy level(n=2-7)can be co...
These energy level shifts are non-zero which indicate that the first order gravitational perturbations can partly remove the degeneracy of the studied states in de Sitter space. We show that it is not possible to use the hydrogen atom as a probe of background curvature of the universe. In ...
Above is the blank energy level diagram which can be used to represent the electrons for any atom under study. Energy level diagrams are known as Grotrian diagrams. It is named after German astronomer Walter Grotrian (from the first half of the 20thcentury). The important observations revealed ...
Now, hydrogen transfer from the electrolyte solvent to the metal oxide cathode has been demonstrated as an operative self-discharge mechanism. Noah P. Holzapfel Veronica Augustyn News & Views29 Jan 2025 Nature Chemistry Volume: 17, P: 163-164 Latest Research and Reviews Harnessing organic ...
The performance of kesterite solar cells is limited by poor extraction of electrons and holes and their recombination. Researchers have now discovered that annealing the device in a hydrogen-containing atmosphere can promote efficient charge extraction by redistributing certain elements like sodium and ox...
Fig. 8(a) shows the influence of the crystal-field parameter on the energy levels of the Mn4+ electrons in the T−S energy-level diagram. The corresponding electron configuration for the 3d3 Mn4+ ion is indicated on its right-hand side. The black and gray data points in Fig. 8(a...
