Nonrelativistic ionization energy for the helium ground state

arXiv:physics/0204079 · doi:10.1103/PhysRevA.66.024501

Abstract

The helium ground state nonrelativistic energy with 24 significant digits is presented. The calculations are based on variational expansion with randomly chosen exponents. This data can be used as a benchmark for other approaches for many electron and/or three-body systems.
