For laboratory kinetic energies between 50 and 200 MeV, we focus on generating an energy-dependent Lorentz covariant parametrization of the on-shell nucleon-nucleon ($\mathit{NN}$) scattering amplitudes in terms of a number of Yukawa-type meson exchanges in first-order Born approximation. This parametrization provides a good description of $\mathit{NN}$ scattering observables in the …
