Abstract In connection with Temple's formula variance minimization yields accurate values especially for groundstate energies of Schrödinger operators with a discrete spectrum. The result in a.u. for the groundstate E 0 of the He-atom in the infinite nuclear mass approximation is −2.90372438655≤E 0≤−2.90372437696 i.e. E 0 is determined with an absolute error smaller than 0.0022 cm−1.
