I first characterize multi-neutron systems as pure-neutron nuclei and as neutron clusters at the surface of nuclei. Then, I show how to probe such a system using the proton-induced quasi-free scatterings in inverse kinematics for a rare-isotope beam. I introduce the ongoing development of experimental setups for such reactions at SAMURAI at RIBF: the STRASSE and the prototype PFAD, where, for...
The long-standing question regarding the existence of a bound four-neutron system, a so-called tetraneutron, was addressed in an experiment at SAMURAI using the MINOS LH2 target. A $^{8}$He beam was used to perform a (p,p$\alpha$) reaction in inverse kinematics at large center-of-mass angles, allowing for the prompt removal of the $\alpha$ and thus minimizing its influence on the 4n system....
Correlations in multi-neutron systems have been fascinating topics in recent nuclear physics. In this presentation, we will present two of new experimental approaches on multi-neutron systems recently performed and planned at RIBF.
First, we explain our experimental study on 3n system via the 3H(t,3He)3n reaction at 170 MeV/u using the SHARAQ spectrometer. We have developed a thick tritiate...
The emergence of cluster structures within the nucleus is a fascinating phenomenon that requires a complete understanding of the nuclear structure and the fundamental nuclear interactions. So far $\alpha$-clustering has dominated cluster state studies among all other possible partitioning due to the large binding energy of the $\alpha$-particle and its inert character. The famous Ikeda diagram...
Investigating the properties of nuclei far from the line of beta-stability is one of the central themes of present day nuclear physics. Of particular interest as the neutron dripline is approached are the changes in shell structure and the correlations that may develop between the valence neutrons. In this presentation we will focus on the structure and neutron-neutron correlations in the...
The lightest nuclei, encapsulating some of the most fascinating systems in the nuclear landscape, have sparked considerable interest in the nuclear physics community. Their structures are characteristically intricate and complex, particularly evident in the $^{4,5}$He nuclei. These structures can be meticulously expounded with the implementation of realistic interactions in a no-core...
The formation of clusters in finite and infinite nuclear systems is an issue of great interest in nuclear physics. Recently, experiments have revealed a negative correlation between alpha-cluster formation and neutron number in Sn isotopes, showing a trend opposite to that theoretically conjectured for Be and B isotopes.
Here, we investigate the cluster formation in Be and B isotopes to...
