摘要
The nonrelativistic ground-state energy of (HeH+)-He-4 is calculated using a variational method in Hylleraas coordinates. Convergence to a few parts in 10(10) is achieved, which improves the best previous result of Pavanello [J. Chem. Phys. 123, 104306 (2005)]. Expectation values of the interparticle distances are evaluated. Similar results for (HeH+)-He-3 are also presented.
