Let n = 3 and >= be a bounded Lipschitz domain in Rn. Assume that the nonnegative potential V belongs to the reverse H older class RHn( Rn) and p. ( 2,8). In this article, two necessary and sufficient conditions for the unique solvability of the Neumann and the Regularity problems of the Schr odinger equation - >= u + Vu = 0 in >= with boundary data in Lp, in terms of a weak reverse H older inequality with exponent p and the unique solvability of the Neumann and the Regularity problems with boundary data in some weighted L2 space, are established. As applications, for any p. ( 1,8), the unique solvability of the Regularity problem for the Schr odinger equation - >= u + Vu = 0 in the bounded ( semi-) convex domain >= with boundary data in Lp is obtained.
