The n-3H and p-3He elastic phase shifts below the trinucleon disintegration thresholds are calculated by solving the four-nucleon problem with three different realistic nucleon-nucleon interactions (the I-N3LO model by Entem and Machleidt, the Argonne v18 potential model, and a low-k model derived from the CD-Bonn potential). Three different methods---Alt-Grassberger-Sandhas, hyperspherical harmonics, and Faddeev-Yakubovsky---have been used and their respective results are compared. For both n-3H and p-3He we observe a rather good agreement between the three different theoretical methods. We also compare the theoretical predictions with the available experimental data, confirming the large underprediction of the p-3He analyzing power.
