Title: Efimov Physics Around the Neutron-Rich Ca 60 Isotope

Abstract

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.
