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...
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...
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...
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...
