Gamow shell model description of exceptional point in $^{7}$ Li

David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel

We report the first identification of an exceptional point (EP) within the Gamow Shell Model in the Coupled Channels representation (GSM-CC). In the spectrum of $^{7}$ Li, an EP is…

Double pole $S$ -matrix singularity in the continuum of $^{7}$ Be

David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel +1

The double pole singularity of the $S$ -matrix, the so-called exceptional point, associated with the $5/ 2^{-}$ doublet of resonances in the spectrum of $^{7}$ Be has been identified in…
