Daniel Phillips (Ohio University)23/10/2017, 13:30Nuclear Structure, Nuclear Reactions and Exotic NucleiParallel Talk
The reaction $^7$Be(p,ฮณ)$^8$B generates most of the high-energy neutrinos emanating from the pp-fusion chain in our Sun. Over the past twenty years there has been a substantial effort to measure its cross section at center-of-mass energies below 500 keV. One goal of this effort was accurate extrapolation of the astrophysical S-factor to solar energies. I will explain our treatment of this...

Proton-rich nuclei in the A$\sim$70 mass region relevant to the astrophysical rp-process manifest exotic structure and dynamics induced by shape coexistence and mixing, competition between like-nucleon and neutron-proton pairing correlations, as well as isospin-symmetry-breaking interactions. Recent results [1-4] concerning the interplay between isospin-symmetry-breaking and...

The evolution of the shell structure when moving away from the stability line is discussed in the present contribution. In particular, the effect of the tensor interaction in the appearance and disappearance of magic numbers and the specific case of $^{78}$Ni. To contribute to the understanding of the case, the level structure of $^{75,77}$Cu was studied in a $\beta$-delayed...

Dr Carlos Ernesto Vargas Madrazo (Facultad de Fรญsica, Universidad Veracruzana, Mexico.)23/10/2017, 15:25Nuclear Structure, Nuclear Reactions and Exotic NucleiParallel Talk
The rare-earth nuclei have well-known collective properties. The theoretical description of these nuclei represents a challenge to nuclear models, due to the enormous dimensions of the valence space, making the problem unmanageable. This leads us to use symmetry-based models, where it is possible to calculate in a free-truncation environment. In this work we present results for the energy...

Spin-isospin excitations can be studied by beta decay and charge exchange reactions in mirror nuclei, shedding light on mirror symmetry, hence we can compare our results on the beta decay of proton-rich nuclei with the results of charge exchange experiments when appropriate targets for the mirror nuclei are available. Accordingly we have performed experiments at GSI and GANIL to study $T_z$...

Despite all the information we have accumulated during the past decades about the structure of $^{12}$C we have not resolved a number of detail, for example, the geometry of its second excited state at 7.65 MeV (0$^+$), the Hoyle-State, has not yet been solved. Recent results have showed a possible 2$^+$ resonance between 9-12 MeV that could be related with a collective rotational or...

Studies on magnetic moments and life-times of exotic nuclei have unveil properties which have leaded to the deeper understanding of the nature and behavior of the nuclear potential. During last years, the alpha-transfer technique has been useful for the study of properties of nuclear species which cannot be created with the current radioactive beam facilities. One of these characteristics, the...

The spectroscopy of heavy nuclei near the $N$=152 and $N$=162 deformed shell gaps provides precious information to improve current predictions of long-lived super-heavy elements in the Island of Stability. Due to deformation, in fact, substates of spherical orbits in the island of stability can be found near the Fermi level in these lighter systems. At the JAEA-Tokai Tandem accelerator, the...

Nuclear reactions induced by neutron-rich radioactive beams have opened new possibilities for studying nuclei far from stability line [1]. The increase of the reaction cross-sections for neutron rich nuclei compared to the stable nuclei can be attributed to their larger nuclear radii. In order to observe this effect a systematic investigation of total reaction cross sections from elastic...

Heavy ion nuclear reaction studies are an important tool to observe and disentangle different and competing mechanisms, which may arise in the different energy regimes. In particular, at relatively low bombarding energy the comparison between pre-equilibrium and thermal emission of light charged particles from hot nuclei is interesting. Indeed, nuclear structure of the interacting partners and...

Fusion reaction play a critical role in stellar evolution and nucleosynthesis [1]. However, the important fusion reaction still carry large uncertainties at Gamow region due to the low cross sections and, the limited theoretical understanding on the mechanisms related to the fluctuations that occur in the cross section [2]. Recently, we investigated $^{12}$C+$^{12}$C system, by making use of...

In the last decades, a renewed attention to clustering in nuclei has emerged due to the study of weakly bound nuclei at the drip lines [1]. Clusters in nuclear systems can be related to their dynamical formation or their structural presence (pre-formation) in nuclei. While for light nuclei several links between cluster emission and its connection with nuclear structure and dynamics have been...

Nucleosynthetic processes in supernovae and X-ray bursts often involve unstable ions and reactions that are difficult to produce at the relevant energies in rare beam facilities. Recent progress in astronomical observations and the chemical evolution of the Galaxy need to be accompanied with similar progress in understanding the relevant properties of rare isotopes through nuclear physics...

NUMEN proposes cross sections measurements of Heavy-Ion double charge exchange reactions as an innovative tool to access the nuclear matrix elements, entering the expression of the life time of Neutrinoless double beta decay (0ฮฝฮฒฮฒ). If detected, such a process would give direct evidence to the Majorana-nature of neutrinos, opening a window to physics beyond the standard model.

Concerning thermal neutron induced fission of uranium 233, using a Monte Carlo simulation, we show how prompt neutron emission from fragments distorts the distribution of charge as a function of final mass and kinetic energy compared with the primary distribution.
