Session 11: Neutron Physics, Nuclear Structure, Reactions and Dynamics
- Sydney Gales (IPN Orsay)
Based on an idea by Carlo Rubbia, the n_TOF facility at CERN has been operating during the last 20 years. it is a neutron spallation source, driven by the 20 GeV/c proton beam from the CERN PS accelerator. Neutrons in a very wide energy range (from GeV, down to sub-eV kinetic energy) are generated by a massive Lead spallation target feeding two experimental areas set at 185 meters (EAR1,...
Beta decay has a direct access to the absolute values of the Fermi and Gamow-Teller transition strengths. The comparison with complementary charge exchange reactions, such as the ($^3$He,t) reaction performed on the mirror stable targets at RCNP Osaka, allows us the investigation of fundamental questions related to the role of the isospin in atomic nuclei. A systematic study of proton-rich...
The spontaneous proton emission from the nuclei at the proton drip-line is a unique tool to investigate the nuclear structure properties in extreme conditions. Furthermore, as the astrophysical rapid proton capture (rp) process is the inverse of proton emission, the study of the latter can provide insights into the possible paths of the rp process [1-3]. However, due to the short half-life,...
Recent lifetime measurements revealed that the B(E2)$_{4^+/2^+}$ ratio is far less than unity in several nuclei in the mass region 160 ≤ A ≤ 170 namely $^{166}$W [1], $^{168}$Os [2], $^{170}$Os [3], and $^{172}$Pt [4]. From a theoretical point of view, the origin and the underlying structure of this anomalous behavior remains unexplained. On the other hand, a quantum phase transition from...
