摘要
An improved quantum Monte Carlo calculation for the ground state of the molecular ion H-3+ gives higher accuracies than previously attained. The nonrelativistic electronic energy for the equilateral triangle configuration of side length 1.6500 bohrs is found to be -1.343 835 +/- 0.000 001 hartrees.
