Electron configuration is the electron arrangement in an atom. We shall focus on The Ground state electron configuration. It is the base to understand the molecular bonding, structures, and properties. The ground-state electron configuration enlightens many different atomic properties from the electrons...
For excited-state aromaticity, a reversal of ground-state aromaticity in the excited triplet state was proposed in 1972, known as Baird’s rule3. Considering cyclic π-conjugated systems in the triplet state as an intermolecular interaction between two radicals, the interaction between two symmetric...
The electron impact ionization cross sections for excited states of Ne-like Ar~8+ and Y~29+ ions are given by the detailed configuration calculation using a Distorted Wave Born Exchange (DWBE) approximation. The results show that it is important to use the detailed configuration for highly char...
Previous work [Mazziotti,Phys. Rev. A68,052501(2003)] examined the accuracy of excited states extracted from ground-state 2-RDMs, which were calculated by full configuration interaction or the variational 2-RDM method. In this work we employ (i) advances in semidefinite programming to treat ...
Multireference symmetry-projected variational approaches for ground and excited states of the one-dimensional Hubbard model We present a multireference configuration mixing scheme for describing ground and excited states, with well-defined spin and space-group symmetry quantum n...

The electron impact excitation cross sections from the lowest metastable state 5p(5)6sJ = 2 to the six lowest excited states of the 5p(5)6p configuration of xenon are calculated systematically by using the fully relativistic distorted wave method. In order to discuss the effects of target state...
