| Abstract: | The influences of q deformation on the nonclassi cal properties of odd q-coherent states in a finite-dimensional Hibert spaces ( FDHS ) case are studied by numerical method. It is found that, while q<1, the s queezing effect appears and antibunching effect disappears in some range of r-2. With q deformation increasing, the squeezing degree is stren gthened and the antibunching effect is weakened. |
