Final-energy sum rules are used to calculate the proton coupling constant λρwith an interpolating proton current. The coupling constant Λρ can be used to calculate the matrix elements for proton decay in the grand unified SU(5) model. The proton lifetime is calculated to be rp= 1028X(M;r/1014GeV)4yr, whereM* isthemassof the X boson.
