N2 - Very accurate analytical expressions for the radiative corrections of unpolarized hyperons semileptonic decays of charged and neutral baryons have been obtained in the recent past. Some of these formulas contain logarithmic singularities at the edges of the Dalitz plot for the three- and four-body decays. These singularities are analyzed and integrated analytically to obtain new divergentless formulas for the energy spectrum of the produced (Formula presented) particle. The new equations contain terms of the order (Formula presented) times the momentum transfer, are applicable to any beta decay process and are suitable for a model-independent experimental analysis.
