    First measurement of a long-lived meson-meson atom lifetime

    First measurement of a long-lived meson-meson atom lifetime In addition to the ordinary atoms, abnormal or exotic atoms serve as tools to study in detail the structure of atoms and their interactions. Different exotic atoms, consisting of other building blocks than electrons, protons and neutrons, have been observed and investigated. The DIRAC collaboration at CERN
