Description
Borromean nuclei are unique bound quantum systems with unbound sub-systems, that tend to appear in neutron-proton asymmetric isotopes at the edges of the nuclear landscape. Such weakly bound few-body systems can provide sensitive grounds for understanding the nuclear force through their structural properties and interaction. This presentation will describe different techniques of reaction spectroscopy measurements with re-accelerated beams at TRIUMF and in-flight beams at RIBF to explore the ground and excited states of these drip-line nuclei.
At the proton drip-line, spectroscopy of $^{20}$Mg from inelastic scattering with a solid D$_2$ target at the IRIS facility at TRIUMF will be discussed. The observation of new states will be presented and compared to new $\it ab ~initio$ theory predictions. The reaction spectroscopy also offers potential to investigate collectivity that will be discussed to understand shell evolution. The presentation will show how a strong sensitivity to the nuclear force emerges from proton elastic scattering of $^{10}$C.
In the neutron-rich domain, defining the low-Z end of the island of inversion around $N$ = 20 remains as an open problem. The presentation will discuss exploration of the ground state features of the drip-line nucleus $^{29}$F using intermediate energy in-flight beams at RIBF.
