Isoscalar dipole coherence at low energies and forbidden E1 strength

P. Papakonstantinou, V. Yu. Ponomarev, R. Roth +1

In 16O and 40Ca an isoscalar, low-energy dipole transition (IS-LED) exhausting approximately 4% of the isoscalar dipole (ISD) energy-weighted sum rule is experimentally known, but…

Thermalization at lowest energies? A view from a transport model

C Hartnack, H Oeschler, J Aichelin

Using the Isospin Quantum Molecular Dynamics (IQMD) model we analyzed the production of pions and kaons in the energy range of 1-2 AGeV in order to study the question why thermal m…

Production of light nuclei, hypernuclei and their antiparticles in relativistic nuclear collisions

A. Andronic, P. Braun-Munzinger, J. Stachel +1

We present, using the statistical model, an analysis of the production of light nuclei, hypernuclei and their antiparticles in central collisions of heavy nuclei. Based on these st…

Ab Initio Theory of Light-ion Reactions

Petr Navratil, Sofia Quaglioni, Robert Roth

The exact treatment of nuclei starting from the constituent nucleons and the fundamental interactions among them has been a long-standing goal in nuclear physics. Above all nuclear…

Three-body forces and shell structure in calcium isotopes

Jason D. Holt, Takaharu Otsuka, Achim Schwenk +1

Understanding and predicting the formation of shell structure from nuclear forces is a central challenge for nuclear physics. While the magic numbers N=2,8,20 are generally well un…

Novel Nuclear Structure Aspects of the Neutrinoless Double Beta Decay

J. Menendez, A. Poves, E. Caurier +1

We explore the influence of the deformation on the nuclear matrix elements of the neutrinoless double beta decay (NME), concluding that the difference in deformation -or more gener…

Ab initio many-body calculations of nucleon scattering on 4He, 7Li, 7Be, 12C and 16O

Petr Navratil, Robert Roth, Sofia Quaglioni

We combine a recently developed ab initio many-body approach capable of describing simultaneously both bound and scattering states, the ab initio NCSM/RGM, with an importance trunc…

Constraints on neutron star radii based on chiral effective field theory interactions

K. Hebeler, J. M. Lattimer, C. J. Pethick +1

We show that microscopic calculations based on chiral effective field theory interactions constrain the properties of neutron-rich matter below nuclear densities to a much higher d…

Nucleon-Nucleon Scattering in a Harmonic Potential

Thomas Luu, Martin Savage, Achim Schwenk +1

The discrete energy-eigenvalues of two nucleons interacting with a finite-range nuclear force and confined to a harmonic potential are used to numerically reconstruct the free-spac…

In-Medium Similarity Renormalization Group for Nuclei

K. Tsukiyama, S. K. Bogner, A. Schwenk

We present a new ab-initio method that uses similarity renormalization group (SRG) techniques to continuously diagonalize nuclear many-body Hamiltonians. In contrast with applicati…

Systematics of binding energies and radii based on realistic two-nucleon plus phenomenological three-nucleon interactions

A. Günther, R. Roth, H. Hergert +1

We investigate the influence of phenomenological three-nucleon interactions on the systematics of ground-state energies and charge radii throughout the whole nuclear mass range fro…

Spin-flip M1 giant resonance as a challenge for Skyrme forces

V. O. Nesterenko, J. Kvasil, P. Vesely +3

Despite a great success of the Skyrme mean-field approach in exploration of nuclear dynamics, it seems to fail in description of the spin-flip M1 giant resonance. The results for d…
