Cluster structures have been found in light unstable nuclei as well as stable nuclei. For instance, neutron-rich Be isotopes show remarkable cluster structures of a 2 alpha core with surrounding excess neutrons. For C isotopes, three-body cluster structures in excited states have been suggested and attracting a great interest. How can we experimentally probe such the cluster structures ? For...

We have recently introduced a new approach, which is meant to be a step towards complete low-lying spectroscopy of odd-mass nuclei. In the first applications, we have limited ourselves to a magic core plus an extra neutron or proton. The model does not contain any free adjustable parameter, but is based on a Hartree Fock (HF) description of particle states and Random Phase Approximation (RPA)...

While uncertainty quantification has been applied to many fields within nuclear theory, it is still relatively unstudied in reaction theory. There are many sources of these uncertainties, including but not limited to the effective potentials used, model approximations and simplifications, and structure functions. Many of these have been investigated [1], however, they have not been...

Time-dependent nuclear density functional theory (TDDFT) is a tool of choice for describing heavy ion collisions. Here we present a study of nuclear focusing on the aspect of nucleonic clustering in the intermediate states. To visualize emergent clusters, we use the nucleonic localization function, which is based on the probability of finding two nuclei with same spin and isospin at a given...

Understanding the interactions of weakly bound nuclei, and their reaction outcomes, is a key challenge in nuclear reactions research. Apart from the well-known channel coupling effects, reaction dynamics involving weakly-bound nuclei has added complexity due the presence of low-lying particle unbound states, not just in the interacting nuclei but also in neighboring nuclei that are populated...

The rapid neutron capture process (r process) is thought to be responsible for the production of roughly half of the heavy elements found in nature, however the site of the r process is unknown and remains one of the most active areas of research in nuclear astrophysics. Testing r-process predictions requires experimental nuclear data inputs including masses, beta-decay properties, and...

Mass measurements of nuclei far from stability provide an important input to nuclear structure studies and simulations of the rapid-neutron capture process (r-process), the proposed mechanism by which many of the elements heavier than iron are created. Since the exact astrophysical site of this process is still under debate, the route by which the chain of neutron captures, photodissociations...

About half of the elements heavier than iron are formed in rapid neutron capture, r-process nucleosynthesis. Mumpower, Surman, McLaughlin, and Aprahamian [1] have identified unknown nuclear observables that can significantly impact final abundances and could also help to constrain the site of the r process. One of these observables are neutron capture rates at late times, freeze-out, in an...

While core collapse supernovae have long captured the attention of physicists and astronomers, surprisingly little is currently known about the nature of the explosion mechanism. This is due to the complexity of the explosion, the large computational requirements for even 2D simulations, and the lack of precise nuclear physics inputs to these models. One of the few methods by which this...
