ground state energynegative ionThe method of hyperspherical harmonics using an adiabatic separation between the hyper-radial coordinate and the hyperspherical angles is applied to the calculation of the ground state of the helium atom and the hydrogen negative ion. For each system the simple adiabatic...
helium ground state energyHy‐CIA generalization of the Hylleraas-Configuration Interaction method (Hy-CI) first proposed by Wang, et al.1, the Exponentially Correlated Hylleraas-Configuration Interaction method (E-Hy-CI) in which the single rij of an Hy-CI wave function is generalized to a ...
Ground State of the Helium Atom Physical Review Pub Date : 2 November 1956 , DOI: 10.1103/physrev.105.1490 Toichiro Kinoshita The energy level of the ground state of atomic helium is restudied in detail. The nonrelativistic part is treated by the conventional Ritz variation technique. However,...
Perturbation calculations of the helium ground state energy Chemical Physics Letters(IF2.8)Pub Date : 1971, DOI:10.1016/0009-2614(71)80248-8 M.E. Riley , A. Dalgarno A comparison is presented for the ground state of the helium atom of high order Rayleigh-Schrödinger perturbation theories bas...
THE purpose of the present note is to suggest that the discrepancy between the measurements of helium-like spectra made by F. Tyrén and by H. Flemberg1, on one hand, and the theoretical calculations made by E. Hylleraas (non-relativistic) and by me2(relativistic corrections) on the other...
3.3.3.2 The ground state of solid helium The approach outlined above has been used to compute the ground state energy E0 and Pair Distribution Functions (PDF) of the hexagonally packed solid 4He at the density ρ = 4.61421 × 10−3 a0−3, following the setup of and using the classical...
An explicitly correlated wave function is applied to variationally solve the Schrodinger equation within the Born-Oppenheimer approximation for the ground state of the helium dimer. The total electronic energy E as a function of the internuclear distance R is calculated for a wide range of R. An...
