    "abstract": "We present a new chiral expansion scheme for the nucleon-nucleon scattering\namplitude which preserves unitarity exactly. Our effective field theory builds\non the power counting rules for 2-nucleon reducible diagrams proposed in\n\\cite{lutz}. We evaluate the leading order terms of the isospin one scattering\namplitude and elaborate in detail on the $^1S_0$ phase shift. Our chiral\ndescription of the $^1S_0$-phase shift does compete in quality with modern\nphenomenological nucleon-nucleon potentials. We describe elastic and inelastic\nscattering quantitatively up to laboratory energies of $E_{\\rm lab} \\simeq 600$\nMeV.",
