    "abstract": "In extracting deformation parameters from multipole moments for deformed\nnuclei, one commonly uses the formulas which are based on a sharp-cut density\ndistribution. We discuss a possible ambiguity for this procedure and clarify\nthe role of diffuseness parameter of the density distribution. For this\npurpose, we use a deformed Woods-Saxon density as well as a density\ndistribution obtained from the self-consistent relativistic mean-field (RMF)\nmodel. We show that the formula using a root-mean-square radius instead of a\nsharp-cut radius requires a large correction due to a finite surface\ndiffuseness parameter even for stable nuclei. An implication to neutron-rich\nnuclei is also discussed.",
