Squeezing and antibunching effects of Leading terms odd and even coherent states are discussed. The conditions of squeezing and antibunching effect are found, and these photon statistical characteristics are very different from those of the ordinary odd and even coherent states.

In contrast to coherent states \ensuremath{\Vert}\ensuremath{\alpha}〉 which have zero Hanbury Brown and Twiss Effect [i.e., ${g}^{(2)}$(0)=1], it is shown that generalized coherent states \ensuremath{\Vert}n,\ensuremath{\alpha}〉 are antibunched for \ensuremath{\Vert}\ensuremath{\alpha}${\ensuremath{\Vert}}^{2}$(1/2). The range of values for \ensuremath{\alpha} (real) in terms of the squeezing parameter r (real) for the squeezed coherent state \ensuremath{\Vert}\ensuremath{\alpha},r〉 in order to exhibit bunching and antibunching are obtained. The conditions and the exact range of values for r and \ensuremath{\alpha} for a given n for generalized squeezed coherent states \ensuremath{\Vert}n,\ensuremath{\alpha},r〉 to exhibit bunching and antibunching are also obtained.

Based on the even and odd coherent states, the present paper is to construct the even and odd q-coherent states and study their important optical statistics properties (squeezing and antibunching). We have found that the squeezing may occur with the even q-coherent states but no antibunching effect. However, for the odd q-coherent states there is antibunching but no squeezing for all finite-q values.
