In this paper, we prove that if an almost co-Kähler manifold of dimension greater than three satisfying
-Einstein condition with constant coefficients is a Ricci soliton with potential vector field being of constant length, then either the manifold is Einstein or the Reeb vector field is parallel. Let
be a non-co-Kähler almost co-Kähler 3-manifold such that the Reeb vector field
is an eigenvector field of the Ricci operator. If
is a Ricci soliton with transversal potential vector field, then it is locally isometric to Lie group
of rigid motions of the Minkowski 2-space.
