We studied the atomic momentum distribution for a superposition of Bloch states spreading in the lowest band of an optical lattice after the action of the standing wave pulse. By designing the imposing pulse on this superposed state, an atomic moment

We report the observation of quantum dynamical oscillations of ultracold atomic gases in the $F$ and $D$ bands of an ordinary optical lattice. We are able to control the Bragg reflections at the Brillouin-zone edge up to the third order. As a result,
