ABSTRACT. The main goal of the paper is to illustrate the significance
of the work Laptev-Naboko-Safronov [11]. We consider the
Schr\"odinger operator $-\Delta+V$ for $d\geq 3$. We prove that
the a.c. spectrum is essentially supported by $(-\infty,\infty)$
under assumption that $V\in L^{d+1}$ and the Fourier transform
$\hat{V}$
is square integrable near the origin.
