Non-symmetrized hyperspherical harmonic basis for -bodies
M. Gattobigio, A. Kievsky, M. Viviani
The use of the hyperspherical harmonic (HH) basis in the description of bound states in an -body system composed by identical particles is normally preceded by a symmetrization…
Thermal neutron captures on and He
L. Girlanda, A. Kievsky, L. E. Marcucci +3
We report on a study of the and He radiative captures at thermal neutron energies, using wave functions obtained from either chiral or conventional two- and three-nucle…
Proton-3He elastic scattering at low energies and the "A_y Puzzle"
M. Viviani, L. Girlanda, A. Kievsky +2
The Kohn variational principle and the hyperspherical harmonic technique are applied to study p-3He elastic scattering at low energies. Preliminary results obtained using several i…
Variational description of continuum states in terms of integral relations
A. Kievsky, M. Viviani, P. Barletta +2
Two integral relations derived from the Kohn Variational Principle (KVP) are used for describing scattering states. In usual applications the KVP requires the explicit form of the…
Comparative study of three-nucleon force models in systems
A. Kievsky, M. Viviani, L. Girlanda +1
Using modern nucleon-nucleon interactions in the description of the nuclei, it is not possible to reproduce both the three- and four-nucleon binding energies simultaneously…
Relativity constraints on the two-nucleon contact interaction
L. Girlanda, S. Pastore, R. Schiavilla +1
We construct the most general, relativistically invariant, contact Lagrangian at order Q^2 in the power counting, Q denoting the low momentum scale. A complete, but non-minimal, se…
