Abstract

A derivation of the exact analytical expressions for the critical current versus magnetic-field-diffraction pattern of ``electrically'' small annular Josephson junctions is presented. These formulas have been recently used to fit experimental data [N. Martucciello and R. Monaco, Phys. Rev. B 54, 9050 (1996)]. They include, as a special case, the approximate analytical results previously published [N. Martucciello and R. Monaco, Phys. Rev. B 53 3471 (1996)].
