    "abstract": "In this paper we have applied the cluster-expansion ansatz for the wave\noperator \\Omega which incorporates the orbital relaxation and correlation\neffects in an efficient manner. We have used both ordinary and normal ordered\ncluster operator (\\Omega) to compute the ionization potential for different\nstates of Ne, Ar, and Kr. The result in our calculation clearly shows how the\nrelaxation and correlation effects play the role in determining the ionization\npotential, one of the interesting aspects in theoretical spectroscopy.",
