    Advances in the ab initio description of nuclear three-cluster systems

    Carolina Romero-Redondo🇺🇸 · Sofia Quaglioni🇺🇸 · Petr Navrátil🇨🇦 · Guillaume Hupin🇫🇷

    We introduce the extension of the ab initio no-core shell model with continuum to describe three-body cluster systems. We present results for the ground state of 6He and show improvements with respect to the description obtained within the no-core shell model and the no-core shell model/resonating group methods.

    Relativistic few-body methods

    Wayne Polyzou🇺🇸

    I discuss the role of relativistic quantum mechanics in few-body physics, various formulations of relativistic few-body quantum mechanics and how they are related.

    Two neutron decay of 16Be

    A.E. Lovell · F.M. Nunes · I.J. Thompson

    Recently, the first example of two-neutron decay from the ground state of an unbound nucleus, Be, was seen. Three-body methods are ideal for exactly treating the degrees of freedom important for these decays. Using a basis expansion over hyperspherical harmonics and the hyperspherical R-matrix method, we construct a realistic model of Be in order to investigate its decay mode and the role of the two-neutron interaction. The neutron-Be interaction is constrained using shell model predictions. We obtain a ground state for Be that is over-bound by approximately 1 MeV with a width of approximately 0.23 MeV. This suggests, that for such systems, the three-body force needs to be repulsive.
