用反相关法计算了自由电子气体基态的能量和波函数。结果表明，所得的结果与盖斯凯尔所得的结果是一致的（见《物理学进程》）。Soc。，第77卷，第1182页（1961）)，当近似与Gaskell所采用的近似相似时，使用标准变分方法。
The transcorrelated method is applied to the calculation of the energy and wavefunction of the ground-state of the free-electron gas. It is shown that the results obtained are identical to those obtained by Gaskell (see Proc. Phys. Soc., vol.77, p.1182 (1961)), using the standard variational method when approximations similar to those employed by Gaskell are made.
