## Abstract It is shown that trial functions involving Padé approximants yield satisfactory results for the ground state of the helium atom. In particular, the five‐parameter form reproduces the best variational function of the type Ψ = __e__^__–zs__^ϕ(__u__) obtained numerically, to a remarkable e
