| Abstract | |
We report a study on the low-energy properties of the elastic s-wave scattering of a neutron (n) in the carbon isotope C-19 near the critical condition for the occurrence of an excited Efimov state in the three-body n-n-C-18 system. For the separation energy of the two halo neutrons in C-20 we use the available experimental data. We also investigate to which extent the universal scaling laws, strictly valid in the zero-range limit, will survive when using finite-range interactions. By allowing to vary the n-C-18 binding energy, a scaling behavior for the real and imaginary parts of the s-wave phase-shift delta(0) is verified, emerging some universal characteristics given by the pole-position of k cot(delta(R)(0)) and effective-range parameters.
