    "abstract": "As a first result of two new partial-wave analyses, one of the pp and another\none of the np scattering data below 500 MeV, we report a study of the\nlong-range chiral two-pion exchange interaction which contains the chiral\ncoupling constants c1, c3, and c4. By using as input a theoretical value for c1\nwe are able to determine in pp as well as in np scattering accurate values for\nc3 and c4. The values determined from the pp data and independently from the np\ndata are in very good agreement, indicating the correctness of the chiral\ntwo-pion exchange interaction. The weighted averages are c3 = -4.78(10) / GeV\nand c4 = 3.96(22) / GeV, where the errors are statistical. The value of c3 is\nbest determined from the pp data and that of c4 from the np data.",
