The theoretical groundwork for interpretation of the structures of neutron rich Ni, Cu, Zn, Ga, Ge, As, Se and Br N = 50 isotones was laid by my colleague Xiangdong Ji and the late Hobson Wildenthal [1]...
In this contribution, we present measurements of the nuclear magnetic dipole moments and nuclear electric quadrupole moments of the 113-131In isotope chain, performed using the Collinear Resonance Laser Spectroscopy experiment at ISOLDE, CERN.
We show that the electromagnetic properties of the neutron-rich indium isotopes significantly differ at N = 82 compared to N < 82, despite the single...
We present the reduced basis method (RBM) - a dimensionality reduction technique - as a tool for developing emulators for equations with tunable parameters within the context of the nuclear many-body problem. The RBM uses a basis expansion informed by a set of solutions for a few values of the model parameters and then projects the equations over a well-chosen low-dimensional subspace. We have...
Atomic nuclei are remarkable mesoscopic systems where single nucleon excitations coexist and interact with numerous collective features such as pairing correlations, clustering, shape dynamics, and collectivities related to decay.
In this work we report our recent progress in studies of coherent and chaotic excitations in nuclear medium. We discuss pairing and many-body correlations,...

A better quantitative understanding of β-delayed neutron emission rates and spectra is relevant for nuclear structure, astrophysics, and reactor applications: β-delayed neutrons provide valuable information on the β-decay process, are needed in network calculations for understanding the stellar nucleosynthesis process, and can improve the understanding of the kinematics and safety of new...
