Superheavy nuclei (SHN) with an extremely large number of protons (e.g., up to Z = 126) remain to be one of the main topics in nuclear physics [1]. One of the ultimate goals of this research is to explore the fission-stability of SHN at around Z = 114 − 126 and N = 184, where the next shell closures are predicted to occur [1]. The fission half-lives of those SHN were predicted to be much...
The MNT reaction allows us to produce many fissioning nuclei, including neutron-rich nuclei, which cannot be populated by other reactions. Also, excitation energy of compound nucleus distributes widely. These properties are used to obtain fission-fragment mass distribution (FFMDs) for many nuclides as well as their excitation-energy dependence [1,2,3]. The experiments were carried out at the...
Neutron-rich Ca isotopes towards neutron number N = 34 are pivotal for exploring the evolution of the fp-shell orbitals [1]. Beyond the N = 28 shell gap at 48Ca, new magic numbers at N = 32 and 34 were established through spectroscopy of low-lying states [2] and mass measurements [3]. Most recently, the spatial extension of the 1f7/2 and 2p3/2 neutron orbitals was determined via a one-neutron...
The Coupled Channels (CC) model successfully explained the strong enhancement of sub-barrier fusion cross sections as well as the observed structures in the barrier distributions for many systems. However, there are several mechanisms whose influence on the fusion is still not clear, as the role of weak (non-collective excitations) reaction channels. The experimental barrier distributions of...
Heavy-ion fusion reactions are essential to investigate the fundamental problem of quantum tunnelling of many-body systems in the presence of intrinsic degrees of freedom. Studying the fusion of light systems with Q > 0, and the identification of hindrance [a] requires challenging measurements. The investigation of slightly heavier cases allows a reliable extrapolation towards the lighter...
