    "abstract": "The np pair in the spin-singlet state is treated as a Cooper np-pair within\nthe extension of the Nambu-Jona-Lasinio model of light nuclei, describing the\ndeuteron as a Cooper np-pair in the spin-triplet state. For the Cooper np-pair\nin the spin-singlet state we compute the binding energy and express the S-wave\nscattering length of np scattering in the spin-singlet state in terms of the\nbinding energy. The theoretical value of the S-wave scattering length of np\nscattering agrees well with the experimental data.",
