In this paper we study the existence of multi-bump solutions for the following Choquard equation-Δ u+(λ a (x)+ 1) u=\displaystyle\big (1| x|^ μ*| u|^ p\big)| u|^ p-2 u in\,\,\, R^ 3,-Δ u+(λ a (x)+ 1) u=(1| x| μ∗| u| p)| u| p-2 u in R 3, where μ ∈ (0, 3), p ∈ (2, 6-μ) μ∈(0, 3), p∈(2, 6-μ), λ λ is a positive parameter and the nonnegative continuous function a (x) has a potential well Ω:= int (a^-1 (0)) Ω:= int (a-1 (0)) which possesses k disjoint bounded components Ω:= ∪ _ j= 1^ k Ω _j Ω:=∪ j= 1 k Ω j. We prove that if the parameter λ λ is large enough, then the equation has at least 2^ k-1 2 k-1 multi-bump solutions.
