This book covers the structure and dynamics of atomic nuclei in terms of nucleons, pions, and quarks, all within a unified treatment of the nuclear response to an electromagnetic probe. The basic formalism is presented to describe the electromagnetic field and its interaction with nuclear matter for both real and virtual photons. Nuclear response is then analyzed in terms of structure functions in the case of inclusive and semi-inclusive inelastic electron scattering. The discussion covers pion production and one- or two-nucleon emission and compares the results with available data. The formalism is also extended to incident polarized electrons, polarized targets and nuclear recoil polarization. It contains a comprehensive description of photonuclear reactions at intermediate energies and a review of experimental data and previous theoretical approaches.

The textbook we offer to the reader is based on a two-term course of lec tures, "Electromagnetic Response of Material Media," that the authors gave for a number of years to the final-year students of the Physics Depart ment of Moscow University. This course built on courses in quantum electronics, nonlinear optics and theoretical fundamentals of quantum radiophysics; students are as sumed to have mastered the fundamentals of quantum mechanics, laser physics and nonlinear optics. The essential core of the course, and hence of the book, is the current general theory of electromagnetic response of a nonrelativistic medium. The main aspects are presented in Chapters 1 and 2. The second part is devoted to more traditional topics which students learn in this course of lectures and also in the course "Condensed Matter Physics" for students who choose to major in radiophysics and laser physics; this course is also taught by the authors at the Physics Department. This volume was intended as a text for students and, as such, does not cite original publications. We decided to provide a list of additional recommended literature, mostly of well known, easily accessible textbooks.

Precise measurement of neutrino oscillations, and hence the determination of their masses demands a quantitative understanding of neutrino-nucleus interactions. To this aim, two-body meson-exchange currents have to be accounted for along within realistic models of nuclear dynamics. We summarize our progresses towards the construction of a consistent framework, based on quantum Monte Carlo methods and on the spectral function approach, that can be exploited to accurately describe neutrino interactions with atomic nuclei over the broad kinematical region covered by neutrino experiments.

In this thesis, which is conducted in the field of few-body nuclear physics, we apply the recently developed method of the Lorentz Integral Transform (LIT) to the study of inelastic electromagnetic reactions on light nuclei. The two basic electromagnetic reactions, i.e. nuclear photoabsorption and electron scattering off nuclei, are treated. The LIT enables one to perform exact calculations, avoiding the complication of the explicit evaluation of the continuum final states and reducing the problem to the solution of a bound state like equation. With this method the final state interaction is fully taken into account. The bound state like calculations are performed with an hyperspherical harmonics expansion, whose convergence is accelerated by building an effective interaction in the hyperspherical formalism (EIHH). In this work we present the first microscopic calculation of the total photoabsorption cross sections below pion production of 6Li, 6He and 7Li. The calculations are performed with simple central semirealistic NN-interactions, which simulate partially the tensor force, since they reproduce binding energies of two and three-body nuclei. The obtained photoabsorption cross section of 6Li shows a single broad giant dipole resonance, while the one of 6He presents two well separated peaks corresponding to the break up of the neutron halo and the alpha-core, respectively. The comparison with experimental data shows that the addition of a P-wave interaction improves substantially the agreement with data. For 7Li a single broad giant dipole resonance is found and a good agreement with the available experimental data is achieved. As concerns the electron scattering reaction, we present a calculation of the longitudinal and transverse response functions for 4He in the quasi-elastic region at medium momentum transfers. A non-relativistic model for the electromagnetic charge and current excitation operators is used. The calculation is performed with a semirealistic in.

Nuclear physics is presently experiencing a thrust towards fundamental phy sics questions. Low-energy experiments help in testing beyond today's stan dard models of particle physics. The search for finite neutrino masses and neutrino oscillations, for proton decay, rare and forbidden muon and pion de cays, for an electric dipole moment of the neutron denote some of the efforts to test today's theories of grand unification (GUTs, SUSYs, Superstrings, ... ) complementary to the search for new particles and symmetries in high-energy experiments. The close connections between the laws of microphysics, astrophysics and cosmology open further perspectives. This concerns, to mention some of them, properties of exotic nuclei and nuclear matter, and star evolution; the neutrino and the dark matter in the universe; relations between grand unification and evolution of the early universe. The International Symposium on Weak and Electromagnetic Interactions in Nuclei (W.E.LN. 1986)' held in Heidelberg 1-5 July 1986, in conjunction with the 600th anniversary of the University of Heidelberg, brought together experts in the fields of nuclear and particle physics, astrophysics and cosmol ogy.
