20. Performances of AGATA at high energies

We propose to conduct an experiment aimed at assessing the performance of AGATA at energy levels of up to 4.8 MeV. Investigating AGATA’s response to highly energetic gamma rays, specifi- cally focusing on efficiency, resolution, and the performance of the tracking algorithm, is a matter of considerable interest within the scientific community. However, such an evaluation has not yet been...

3. Collectivity study in neutron-rich Indium and Silver isotopes via lifetime measurement

Much attention has been attracted to the "Southwest" of the double-magic $^{132}$Sn in the past 30 years. Even though the $N$ = 82 shell closure is still robust from $^{132}$Sn to $^{128}$Pd, the evolution of proton and neutron orbitals has been discovered in this region. Our knowledge of the single particle orbitals can help to examine the nuclear force and constrain shell model parameters,...

17. Highly deformed bands in europium isotopes and identification of new isotopes

Dr Conor Sullivan (University of Liverpool)

03/10/2023, 12:20

In this letter of intent, we set out a case to search for excited states in the isotopes, $^{135}$Eu, $^{136}$Eu, $^{137}$Eu, $^{138}$Eu and $^{139}$Eu. Information on excited states for most of these nuclides is relatively sparse, presenting a fertile ground for discovery in a region exhibiting isomerism, shape coexistence, and superdeformation. This experiment aims to elucidate and...

6. Accessing neutron-rich nuclei close to 208Pb

Franco Galtarossa (Istituto Nazionale di Fisica Nucleare)

03/10/2023, 12:40

The region of the nuclear chart close to the doubly-magic ($Z=82,N=126$) $^{208}$Pb nucleus is at the center of extensive experimental and theoretical investigations, connected both to nuclear structure, astrophysics and reaction mechanism studies. The experimental information concerning low-lying excited states of nuclei in this region is still extremely scarce and in most cases limited to...

13. Lifetime Measurements in Neutron-rich Pb Isotopes. Exploring the Nuclear Structure around the N=126 Shell

Benito Gongora Servin (Istituto Nazionale di Fisica Nucleare)

03/10/2023, 13:00

The neutron-rich part of the nuclear chart and, in particular, the regions around double-shell closures have been studied in detail revealing intriguing phenomena. However, around the $^{208}$Pb nucleus, there is still a lack of spectroscopic information, especially regarding lifetimes of nuclear excited states. Large shell model calculations performed for Pb isotopes typically reproduce the...
