The onset of fluctuations into the superconducting state, as identified bythe appearance of a local minimum in the resistance versus temperature, isfound to be coincident with the characteristic activation energy ofnormal-state conduction falling to a value of the order of the superconductingenergy gap of the material at /ital T/=0. The model of conduction used isvariable-range hopping with a Coulomb gap, appropriate to granular metals.
