Abstract
Amplitude of the Coulomb blockade oscillations is calculated for a single-m ode Josephson junction with large electron transparency D. It is shown that the Coulomb blockade is suppressed as D --> 1. The suppression is describe d quantitatively in terms of the Landau-Zener transition in imaginary time.
