Efimov Physics Around the Neutron-Rich Ca-60 Isotope
Artikel i vetenskaplig tidskrift, 2013

We calculate the neutron-Ca-60 S-wave scattering phase shifts using state of the art coupled-cluster theory combined with modern ab initio interactions derived from chiral effective theory. Effects of three-nucleon forces are included schematically as density dependent nucleon-nucleon interactions. This information is combined with halo effective field theory in order to investigate the Ca-60-neutron-neutron system. We predict correlations between different three-body observables and the two-neutron separation energy of Ca-62. This provides evidence of Efimov physics along the calcium isotope chain. Experimental key observables that facilitate a test of our findings are discussed.
