Two- and Three-Electron Atoms and Ions, functions for these systems, perturbed and unperturbed wave functions, based on their general properties. In this we expect the asymptotic region where one of the electrons is far away, to be an important domain. We therefore analyse the the problem in two stages.

Asymptotically Correct Thomas-Fermi Model Density,ity. It can be regarded as a statistical model with the local density deduced from phase space considerations. Alternatively, the local density can be obtained from the WKB radial wave functions in the classically allowed region. This approach makes it clear that the model is not accurate for atoms 作者: 提名 時間: 2025-3-22 09:35
Molecules and Molecular Ions with One and Two Electrons,In general the analysis of these systems is based on the Born-Oppenheimer approximation that the electronic wave function can be developed with localized nuclei. The energy eigenvalue equation for H. is separable in terms of elliptic coordinates and one has essentially exact numerical solutions.

Proton and Neutron Densities in Nuclei,by the results in (2.15). Here we develop simple expressions for proton and neutron densities in nuclei and show that the surface properties of nuclei, such as surface thickness, can be understood in terms of the asymptotic behaviour of the density [110, 111].作者: 威脅你 時間: 2025-3-24 08:52 作者: 朦朧 時間: 2025-3-24 11:18
Using the Popfly Block Creator,when the two electrons are close to each other. We obtain the energies and polarizabilities of the two electron atom and ions in the ground state and also obtain the energies of some excited states. We then describe a three electron wave function for Li and its isoelectronic series, based on the two electron wave functions.作者: BOGUS 時間: 2025-3-24 16:22

Finally we discuss some general properties of matrix elements involved in their calculations and use these to obtain reliable values for polarizabilities and dispersion coefficients of some atoms.作者: 斜 時間: 2025-3-24 21:05
