nucleon-nucleon interaction; chiral constituent quark model
Abstract :
[en] We study the short range nucleon-nucleon interaction in a non-relativistic chiral constituent quark model by diagonalizing a Hamiltonian containing a linear confinement and a Goldston boson exchange interaction between quarks. A finite siw-quark basis obtained from single particle cluster model states was previously used. Here we show that the configurations which appear naturally through the use of molecular orbitals, instead of cluster model states, are more efficient in lowering the six-quark energy.
