With regard to the importance of the quantum interference effect on the interaction of various atomic configurations with the superposition of standard coherent states (for example standard even coherent states), in this article the interaction of a standard even coherent state with a &Xi-configuration three-level atom is studied and the non-classical properties including sub-Poissonian photon statistics and the first order and amplitude-squared squeezing has been investigated. In addition to existence of the first-order squeezing as well as amplitude-squared squeezing, in some intervals of the interaction time, the detection of sub-Poissonian photon statistics at all interaction time, is an important non-classical property of such an interaction system.
