    "abstract": "We propose a coordinate-space regularization of the three-body problem with\nzero-range potentials. We include the effective range and the shape parameter\nin the boundary condition of the zero-range potential. The proposed extended\nzero-range model is tested against atomic helium trimers and is shown to\nprovide an adequate quantitative description of these systems.",
