We examine charging effects for Cooper pairs in ultrasmall Josephson junctions. For small ratio of Josephson coupling energy to charging energy the current-voltage characteristics show a Coulomb gap for Cooper pair tunneling. We observe tunneling of Cooper pairs at voltages where resonance with envi
The finite temperature I-V-;:haracteristic of a normal tunnel junction coupled to its electromagnetic environment is calculated. It is shown that due to quantum fluctuations of the charge the Coulomb gap is only observable provided the impedance Z(w) of the environment exceeds the resistance quantum
