The method of effective interaction, traditionally used in the framework of an harmonic oscillator basis, is applied to the hyperspherical formalism of fewâ€“body nuclei (A = 3 Ã· 6). The separation ofâ€¦ (More)

The recently developed effective interaction method for the hyperspherical harmonic formalism is extended to noncentral forces. Binding energies and radii of threeand four-body nuclei are calculatedâ€¦ (More)

We present a generalization of the hyperspherical harmonic formalism to study systems made of quarks and antiquarks of the same flavor. This generalization is based on the symmetrization of theâ€¦ (More)

The 4He total photoabsorption cross section is calculated with the realistic nucleon-nucleon potential Argonne V18 and the three-nucleon force (3NF) Urbana IX. Final state interaction is includedâ€¦ (More)

The nuclear neutron-proton contact is introduced, generalizing Tan's work, and evaluated from medium energy nuclear photodisintegration experiments. To this end we reformulate the quasideuteron modelâ€¦ (More)

Six-body inelastic reactions are calculated microscopically including the full six-nucleon final state interaction. The total cross sections of gamma+ (6)He ( (6)Li)-->X are considered as examples.â€¦ (More)

The physics of charm has become one of the best laboratories exposing the limitations of the naive constituent quark model and also giving hints into a more mature description of meson spectroscopy,â€¦ (More)

Two conceptually different hyperspherical harmonics expansions are used for the calculation of the total He photoabsorption cross section. Besides the well known method of CHH the recently introducedâ€¦ (More)

Using the Lorentz Integral Transform (LIT) method we compare the results for the triton total photodisintegration cross section obtained using the Correlated Hyperspherical Harmonics (CHH) and theâ€¦ (More)
