We consider the mass concentration phenomenon for the L-2-critical nonlinear Schrodinger equations of higher orders. We show that any solution u to iu(t) + (-Delta) alpha/2 u - +/-vertical bar u vertical bar 2 alpha/d u, u(0, .) epsilon L-2 for alpha > 2, which blows up in a finite time, satisfies a mass concentration phenomenon near the blow-up time. We verify that as alpha increases, the size of region capturing a mass concentration gets wider due to the stronger dispersive effect.
