N2 - In this paper, the photon added coherent states for nonharmonic oscillators in a nonlinear Kerr medium are introduced and the number- phase winger function of the introduced states are discussed. Then, the phase properties of these states are investigated by using Pegg-Barnett formalism and also their number-phase squeezing is studied M3 ER -
