157. Nuclear physics in stellar lifestyles with the Trojan Horse Method

Aurora Tumino (LNS)

Invited

Understanding energy production and nucleosynthesis in stars requires a precise knowledge of the nuclear reaction rates at the energies of interest. To overcome the experimental difficulties arising from the small cross sections at those energies and from the presence of the electron screening, the Trojan Horse Method has been introduced. The method represents one of the most powerful tools...

123. Optical Potentials Derived from Nucleon-Nucleon Chiral Potentials at N4LO: Comparison between Phenomenological and Microscopic Optical Potentials

Dr Paolo Finelli (University of Bologna)

Oral

Proton elastic scattering is a very important process to understand nuclear interactions in finite nuclei. Even if this process has been extensively studied in the last years, a consistent microscopic description is still under development.
We want to study the domain of applicability of microscopic two-body chiral potentials in the construction of an optical potential, derived as the...

162. Intertwined quantum phase transitions in the Zr isotopes

Prof. Amiram Leviatan (The Hebrew University)

Oral

Most of the attention in the study of quantum phase transitions (QPT) in nuclei, has been devoted to shape phase transitions in a single configuration (denoted Type I), described by a single Hamiltonian, $\hat{H}(\xi) \!=\! \left( 1\!-\!\xi \right)\hat{H}_{1} + \xi \hat{H}_{2}$, where $\xi$ is the control parameter. A different type of phase transitions (denoted Type II) occurs when two (or...

176. Gamma spectroscopy of neutron-rich isotopes in the A = 100 region produced in fission induced by cold neutrons with new FIPPS array

Dr Lukasz Iskra (INFN sezione di Milano)

Oral

The occurrence of shape coexistence in nuclei with N = 58 and 59, suggests that the evolution of the deformation is a gradual process. Our goal was to study N = 57, 96Y isotope where only a few states were known. Additionally, we decided to investigate whether deformed structures are present in the 94Y nucleus which lies 5 neutrons away from the N = 60 boundary and in the 97Y with 59 neutrons....

53. Chiral three-body force and monopole properties of shell-model Hamiltonian

Tokuro Fukui (INFN-Napoli)

15/05/2019, 12:40

Oral

We show an evolution to derive the shell-model effective Hamiltonian employing two- and three-body interactions based on the chiral effective field theory. A new way to calculate three-body matrix elements of the chiral interaction with the nonlocal regulator is given.

We apply our framework to the p-shell nuclei and perform benchmark calculations to compare our results with those by an ab...
