It is proved that the discrete spectrum of the operator $-\Delta+q(x)$ in the space
$L_2(E_{2k})$ ($k\geqslant1$) where $q(x)$ is a measurable complex-valued function
satisfying the condition $|q(x)|\leqslant Ce^{-\varepsilon|x|}$,
having no finite limit points, and for $k=1$ the discrete spectrum consists of a finite number
of points.
