Study of Electron Correlation in the Hydride Ion

Abstract
The influence of angular correlation on the wavefunction and energy of the hydride ion has been investigated by solving various angular limit equations through the I limit. Several one‐electron properties are presented along with three‐dimensional plots of the wavefunction. The extrapolated energy is −0.527743 a.u. compared to the exact value of −0.527751 a.u.
