Their momentum dependence is explicitly determined without additional assumptions and extrapolations in the whole kinematical range of the momentum transfer squared $q^2$. The differential $\\Lambda_c\\to p l^+l^-$ decay branching fractions and angular distributions are calculated on the basis of these form factors.
