Abstract
and scattering in the energy range above the but below the thresholds is studied by solving the four-nucleon problem with a realistic nucleon-nucleon interaction. Three different methods—Alt, Grassberger, and Sandhas, hyperspherical harmonics, and Faddeev–Yakubovsky—have been employed and their results for both elastic and charge-exchange processes are compared. We observe a good agreement between the three different methods, thus the obtained results may serve as a benchmark. A comparison with the available experimental data is also reported and discussed.
