Fractional ac Josephson effect in p- and d-wave superconductors.

Presents the results of a study on the fractional alternating current (ac) effect in p- and d-wave superconductors. Information on the fractional frequency of the ac Josephson current; Relationship between the Josephson current and the first power of the electron tunneling amplitude; Use of the frequency spectrum of microwave radiation from the junction in observing the Josephson effect.
