    "abstract": "We show that the well-known negative binomial states of the radiation field\nand their excitations are nonlinear coherent states. Excited nonlinear coherent\nstate are still nonlinear coherent states with different nonlinear functions.\nWe finally give exponential form of the nonlinear coherent states and remark\nthat the binomial states are not nonlinear coherent states.",
