We show that the final-state interaction explains the nontrivialnear-threshold energy dependence of the cross section of the process$e^{+}e^{-}\rightarrow\Lambda_{c}\bar{\Lambda}_{c}$ observed by the Belle andBESIII collaborations. This energy dependence is the result of the mixture of$S$-wave and $D$-wave components of the $\Lambda_{c}\bar{\Lambda}_{c}$ wavefunction due to a tensor interaction. The Coulomb potential is important onlyin the narrow energy region about a few MeV above the threshold of the process.It is shown that the widely used assumption that the impact of the Coulombinteraction on the cross sections of hadron production is reduced to theSommerfeld-Gamow-Sakharov factor is not correct.
