Dynamics of quantum systems embedded in a continuum
TL;DR: In this paper, the relevance of the open quantum system formalism for the description of weakly bound nuclei far from the valley of stability, small droplets of neutral atoms, gas of trapped atoms, open microwave cavities and quantum dots is discussed.

First-forbidden mirror β-decays in A=17 mass region
TL;DR: In this article, the first forbidden β-decay of 17Ne into the "halo" state Jπ = 1/21+ of 17F was studied in the framework of the Shell Model Embedded in the Continuum (SMEC).

Hindrance Phenomena in Unique First- and Third-Forbidden β-Decay
TL;DR: In this paper, the authors examined correlations introduced by the repulsive T = 1 particle-hole force and showed that these correlations explain the experimentally observed hindrance, and in a large proportion of the cases, good numerical agreement was also obtained.
