摘要：

The ground-state energy of positronium negative ions, Ps-, is calculated using double-basis-set Hylleraas functions in which four nonlinear parameters are used. The optimized result of E = -0.524 010 140 465 7 Ry obtained by using 744-term function represents the lowest variational energy for Ps- in the literature to date to our knowledge. The wave function is then used to calculate the positron annihilation rate for Ps-.
