Let H=-{partial_derivative}{sub x}{sup 2}+V(x) be a properly defined Schroedinger operator on L{sub 2}(R) with real potentials of the form V(x)=q(x)+p{sup '}(x) (the derivative is understood in the distributional sense) with some p,q set-membership sign L{sub 2}(R). We prove that the absolutely continuous spectrum of H fills (0,{infinity}) which was previously proven by Deift-Killip for V set-membership sign L{sub 2}(R). We also refine the 3/2-Lieb-Thirring inequality.
