  1. 49. New nuclear three-body clusters φN N

    Solving Faddeev differential equations, binding energies of three-body systems of the type φN N are calculated. Due to the strong attraction between φ-meson and nucleon, suggested in [1] and [2], bound states appear in systems φ + np (singlet and triplet), φ + nn and φ + pp. This indicates on the principal possibility of the formation of new nuclear clusters with increased number of...

  2. 35. Variational calculations for K-few-nucleon systems

    Deeply bound KNN, KNNN and KNNNN states are discussed. The effective force exerted by the K meson on the nucleons is calculated with static nucleons. Next the binding energies are obtained by solving the Schrödinger equation or by variational calculations. The dominant attraction comes from the S-wave \Lambda(1405) and an additional contribution is due to \Sigma(1385). The latter state is...

  3. 54. A journey through exotica in hadronic physics

    The fascination with the exotic transcends all disciplines. Hadronic, or strong interaction physics has not been immune from it. Time and again it has come up with ideas of exotic hadrons. Time and again they turn out to be mirages. But then, once in a while, the exotic materializes, and all the past failures pale into the excitement of those discoveries. I will present a tour through...

  4. 50. Boundary-condition-determined wave functions, and their nodal structure, for few-electron atomic systems
    Prof. Dario Bressanini (Universita' dell'Insubria, Como, Italy)

    Highly compact wave functions with a clear physical meaning for the He atom and He-like isoelectronic ions for Z=1-10 are written as a symmetrized product of exp[(ar+br2)/(1+r)] electron-nucleus terms and an electron-electron Jastrow factor to satisfy the correct asymptotic behavior both at short and large interparticle distances. Some parameters are chosen to satisfy exactly the...

  5. 16. Microscopic Description of Few-Body Systems in the Fermionic Molecular Dynamics Approach
    Dr Thomas Neff (GSI Darmstadt)

    Talks at Critical Stability V (Erice, October 2008)
    Normal
    The Fermionic Molecular Dynamics (FMD) [1] is a microscopic model for the description of nuclei in the p- and sd-shell. Many-body basis states are Slater determinants of Gaussian wave packets localized in phase space. The wave packet basis is very flexible and includes the harmonic oscillator shell model basis as well as Brink-type cluster states as limiting cases. The width of the wave...
