DESCRIPTION:We consider the Schroedinger operator $H_{ta W} = -Delta + t
 a W$\, \nself-adjoint in $L^2(R^d)$\, $d geq 1$. Here $ta$ is a non const
 ant almost periodic function\, while $W$ decays slowly and regularly at in
 finity. We study the asymptotic behaviour of the discrete spectrum of $H_{
 ta W}$ near the origin\, and due to the irregular decay of $ta W$\, we e
 ncounter some non semiclassical phenomena\; in particular\, $H_{ta W}$ ha
 s less eigenvalues than suggested by the semiclassical intuition.\n
