Abstract:
    We present the results of a redshift survey of galaxies in the A3528
    complex, a chain of interacting clusters in the core of the Shapley
    Concentration.

    The spectroscopic observations were performed at the 3.6-m ESO
    telescope at La Silla, equipped with the OPTOPUS multifibre
    spectrograph, on the nights of 1991 March 8-9 (for the Field 10) and
    from 1993 February 23-27.
