ABSTRACT We discuss formation of two-dimensional spatial structures of atoms due to atomic diffraction on two crossed standing electromagnetic fields. This analysis prop osed for V-type atomic configuration und er dispersive atom-field interactions in quantum regime. Localization of the position of atoms passing through standing light wave is initiated by making a quadrature phase measurement on the light fields. We develop the procedure for strong two-dimensional spatial localization of atomic beam within the optical wavelength. Considering atomic spatial localization in the presence of entanglement of two light beams various two-dimensional patterns for V-type atoms are reported. Keywords: Nano-structures, atomic deflection, quadrature measurement 1. INTRODUCTION During the past years, problems of precise spatial quantum measurement of atoms as well as the optical techniques for spatial localization of atoms have been subjects of considerab le interest. These problems have been mainly considered in interactions of atoms with various internal structures of energetic levels with standing electromagnetic fields. In this way, it has been demonstrated that the measurem ent of the state of a standing wave during atom-light interaction may lead to the localization of the position of the deflected atom. Localization of the position of atoms passing through standing light wave by making a quadrature phase measurement on the light field was shown in one-dimensional case
