Comment on “ Compact wave functions for four - electron atomic systems ”
نویسنده
چکیده
The paper by Frolov and Wardlaw [1] that motivated this Comment (“the PRA paper”) is one of a series of contributions [1–4] taking the viewpoint that their electronic-energy computations on small atomic systems provide a basis for study of the so-called 1/Z expansion, i.e., an expansion that describes the nonrelativistic energies (in Hartree units) of the members of an atomic isoelectronic series with nuclear charges Z: E(Z) = a2Z + a1Z + a0 + b1Z−1 + b2Z−2 + · · · .

Biologically Inspired Four Elements Compact Antenna Arrays With Enhanced Sensitivity for Direction of Arrival Estimation
A new four elements compact antenna array is presented and discussed to achieve enhanced phase resolution without sacrificing the array output power. This structure inspired by the Ormia Ochracea’s coupled ears. The analogy between this insect acute directional hearing capabilities and the electrically compact antenna array is used to enhance the array sensitivity to direction of arrival estima...
متن کاملManagement Certainly Matters, and There Are Multiple Ways to Conceptualize the Process; Comment on “Management Matters: A Leverage Point for Health Systems Strengthening in Global Health”
The authors of “Management matters: a leverage point for health systems strengthening in global health,” raise a crucial issue. Because more effective management can contribute to better performing health systems, attempts to strengthen health systems require attention to management. As a guide toward management capacity building, the authors outline a comprehensive set of core management compe...
متن کاملSelecting the tip electron orbital for scanning tunneling microscopy imaging with sub-ångström lateral resolution
We report on scanning tunneling microscopy (STM) studies performed with single crystalline W[001] tips on a graphite(0001) surface. Results of distance-dependent STM experiments with sub-̊angström lateral resolution and density functional theory electronic structure calculations show how to controllably select one of the tip electron orbitals for highresolution STM imaging. This is confirmed by ...
متن کاملChemical Bonding: The Orthogonal Valence-Bond View
Chemical bonding is the stabilization of a molecular system by charge- and spin-reorganization processes in chemical reactions. These processes are said to be local, because the number of atoms involved is very small. With multi-configurational self-consistent field (MCSCF) wave functions, these processes can be calculated, but the local information is hidden by the delocalized molecular orbita...
متن کاملBoundary solutions of the two-electron Schrödinger equation at two-particle coalescences of the atomic systems
The limit relations for the partial derivatives of the two-electron atomic wave functions at the two-particle coalescence lines have been obtained numerically using accurate correlation function hyperspherical harmonic method wave functions. The asymptotic solutions of the proper two-electron Schrödinger equation have been derived for both electron-nucleus and electron-electron coalescence. It ...
