Double pole $S$-matrix singularity in the continuum of $^7$Be
The Gamow shell model locates a double pole S-matrix singularity (exceptional point) for the 5/2^- resonances in 7Be, shown by coalescing wave functions, spectral functions, and singular spectroscopic factors plus electromagnetic transitions.
