Abstract

No-core Gamow shell model (NCGSM) is applied to study selected well-bound and unbound states of helium isotopes. This model is formulated on the complex energy plane and, by using a complete Berggren ensemble, treats bound, resonant, and scattering states on equal footing. We use the density matrix renormalization group method to solve the many-body Schrödinger equation. To test the validity of our approach, we benchmarked the NCGSM results against Faddeev and Faddeev-Yakubovsky exact calculations for 3H and 4He nuclei. We also performed ab initio NCGSM calculations for the unstable nucleus 5He and determined the ground-state energy and decay width, starting from a realistic N3LO chiral interaction.
