In this paper, we study the mass concentration behavior of positive solutions with prescribed -norm for a class of Schrodinger-Poisson equations in {-Delta u - mu u + phi(u)u - broken vertical bar u broken vertical bar (p-2) u = 0, x is an element of R-3, mu is an element of R, -Delta phi(u) = broken vertical bar u broken vertical bar(2), where p is an element of (2, 6). We show that positive solutions with prescribed -norm as which tends to 0 (in some cases) or to (in others), behave like the positive solution of Schrodinger equation in -Delta(u) + u = broken vertical bar u broken vertical bar (p-2) u in R-3.
