Phys. Rev. A 65, 042507 (2002) [5 pages]Benchmark energy calculations on Be-like atomsReceived 9 November 2001; published 1 April 2002 Upper bounds to the nonrelativistic ground-state energies of beryllium isoelectronic ions with 3<~Z<~10 were computed from 1600-term exponentially correlated Gaussian functions. The energies obtained substantially improve over previous variational results known from literature. The mass polarization corrections to the energy are also presented. © 2002 The American Physical Society URL:
