This paper is concentrated on the nonclassical properties of the pair coherent states during the interaction with a three-level Λ-type atom, such as antibunching effect, violation of Cauchy-Schwarz inequality and two-mode squeezing. Meanwhile, we find these nonclassical properties can be enhanced in the case that the atom is selectively measured.
