## Abstract

We consider the blow-up of the solution in H^{1} for the following nonlinear Schrödinger equation: i ∂ ∂tu + Δu = -|u|^{p - 1}u, x ε{lunate} R^{n}, t ≥ 0, (*) u(0, x) = u_{0}(X), x ε{lunate} R^{n}, t = 0, where n ≥2 and 1 + 4/n ≤ p < min { (n + 2) (n - 2), 5}. We prove that if the initial data u_{0} in H^{1} are radially symmetric and have negative energy, then the solution of (*) in H^{1} blows up in finite time. We do not assume that xu_{0} ε{lunate} L^{2}, and therefore our result is the generalization of the results of Glassey [4] and M. Tsutsumi [18] for the radially symmetric case.
