We compute the Yang-Mills vacuum wave functional in three dimensions at weak coupling with O(e 2 ) precision. We use two different methods to solve the Schroedinger functional equation.One of them generalizes to O(e 2 ) the method followed by Hatfield at O(e) [2]. The other uses the weak coupling version of the gauge invariant formulation of the Schroedinger equation and the ground state wave functional followed by Karabali, Nair, and Yelnikov [3]. We compare both results and discuss the differences between them.Xth Quark Confinement and the Hadron Spectrum,
