An accurate few-parameter ground state wave function for the Lithium atom
Nicolais L. Guevara, Frank E Harris, Alexander V Turbiner
A simple, seven-parameter trial function is proposed for a description of the ground state of the Lithium atom. It includes both spin functions. Inter-electronic distances appear i…
A note about the ground state of the hydrogen molecule
A. V. Turbiner, N. L. Guevara
A trial function is presented for the molecule which provides the most accurate (the lowest) Bohr-Oppenheimer ground state energy among few-parametric trial functions (with $…
The molecular ion in a magnetic field in linear parallel configuration
A. V. Turbiner, N. L. Guevara, J. C. López Vieyra
A first detailed study of the ground state of the H molecular ion in linear configuration, parallel to a magnetic field direction, and its low-lying $\Si,Π,\De$ states is car…
