ABSTRACT:
In the proposed experiment, we plan to investigate the properties of nuclei close to the doubly-magic $^{56}$Ni isotope (N = Z = 28) using the Coulomb-excitation method.
Specifically, we propose to study the electromagnetic structure of $^{62}$Ni with the AGATA spectrometer coupled to the SPIDER (+DANTE) heavy-ion detector.
The results of the proposed experiment, along with those from the $^{58,60}$Ni Coulomb-excitation experiments already performed at IJC Lab (Orsay, France) and INFN LNL (Legnaro, Italy) with the Nuball2+DSSD, GALILEO+SPIDER, and AGATA+SPIDER setups, will allow us to bring a crucial experimental input to investigate fundamental aspects of the structure of doubly-magic nuclei and in their vicinity. In particular, with the new Coulomb-excitation data set we will provide further inputs to discuss some open questions, such as:
- Are nuclei nearby doubly-magic isotopes spherical in their ground
states? - What is the reason for the emergence of collectivity close to shell closures?
- What is the potential role of triaxiality in forming deformed shapes in these regions? How “good” is the 28 magic number?
