Abstract
The manifestation of exceptional points in the scattering continuum of an atomic nucleus is studied using the real-energy continuum shell model. It is shown that low-energy exceptional points appear for realistic values of coupling to the continuum and, hence, could be accessible experimentally. Experimental signatures are proposed which include the jump by of the elastic scattering phase shift and a salient energy dependence of cross sections in the vicinity of the exceptional point.
