Abstract
The paper studies the effect of a weak periodic driving on metastable Wanni er-Stark states. The decay rate of the ground Wannier-Stark states as a con tinuous function of the driving frequency is calculated numerically. The th eoretical results are compared with the experimental data of Wilkinson et n l. [Phys. Rev. Lett. 76, 4512 (1996)] obtained for cold sodium atoms in an accelerated optical lattice.
