In this paper, we consider the following Schrodinger-Poisson problem @@@ [GRAPHICS] @@@ where 2* = 6 is the critical exponent in R-3, K is an element of L-1/2 (R-3) and V is an element of L-3/2 (R-3) are given nonnegative functions. When vertical bar V vertical bar(3/2) +vertical bar K vertical bar(1/2) is suitable small, we prove that problem (P) has at least one bound state solution via a linking theorem.
