Using nonlocal $\mathit{NN}$ interactions which reproduce the three-nucleon binding energies, this work investigates the dependence of the theoretical $p\text{−}d$ and $n\text{−}d$ elastic scattering results on the triplet $P$-wave $\mathit{NN}$ interactions. The low-energy tensor analyzing powers $T_{20}$ and $T_{21}$ are found to be also sensitive to the triplet $P$-wave interactions. A link seems to exists between the $N\text{−}N$ and $N\text{−}d$ analyzing powers which makes it possible to define sets of low-energy (between 1 and 100 MeV) modified nonlocal triplet $P$-wave interactions capable of reproducing most of the known experimental $N\text{−}d$ elastic scattering data up to 30 MeV. The same results could be achieved with analogously modified local triplet $P$-wave interactions. Based on these results, a nonlocal interaction is constructed, which reproduces simultaneously the $N\text{−}N$ data and most of the known $N\text{−}d$ elastic scattering experiments up to 30 MeV.
