We consider the scattering problem for the Hartree type equation in ℝnwithn≧2:where $$V(x) = \sum\limits_{j = 1}^2 {\lambda _j |x|^{ - \gamma j} ,(\lambda _1 ,\lambda _2 ) \ne (0,0),\lambda _j \in \mathbb{R}} ,\gamma _j > 0$$ and * denotes the convolution in ℝn. We prove the existence of wave operators inH0,k= {ψ∈L2(ℝn);|x|kψ∈L2(ℝn)} for any positive integerkunder the assumption 1<γ1, γ2<2. This is an optimal result in the sense that the existence of wave operators breaks down if min (γ1, γ2≢1. The case where 1<γ1, γ2= 2 is also treated according to the sign of λ2.
