    "abstract": "The universal curve $\\sigma /A$ of nuclear photoabsorption is investigated\nwithin a Fermi gas model of nuclear matter. An energy range from pion threshold\nup to 400 MeV is considered. The interactions between nucleon, pion, $\\Delta\n$-isobar and photon are considered in the non-relativistic approximation with\ncorrections of the order $1/M$ taken into account with respect to proton mass.\nAnalytical expressions are obtained, in which the influence of nuclear\ncorrelations, two-nucleon contributions and relativistic corrections is studied\nexplicitely. An extension of the model calculation to nucleon knock-out\nreactions is discussed.",
