The FIssion Product Prompt gamma-ray spectrometer (FIPPS) [1] is the new nuclear physics instrument at the Institut Laue-Langevin (ILL). FIPPS takes advantage of an intense “pencil-like” neutron beam (flux 10${^8} \mbox{n}\cdot \mbox{s}^{-1} \mbox{cm}^{2}$) for inducing neutron capture and neutron-induced fission reactions and study the nuclear structure via high-resolution gamma-ray...
Nuclear shape is a sensitive probe of understanding the many-body quantum system and nucleon-nucleon interaction. Shape coexistence was reported in doubly magic 78Ni [1]. Related features such as triaxiality [2] and onset of deformation beyond N = 50 [3,4] were also reported in this mass region. The study of these phenomena plays a crucial role in understanding the limit of nuclear stability...
$^{212}$Po has two protons and neutrons outside the doubly-magic nucleus $^{208}$Pb and it may be assumed that the nuclear structure can be well described within the shell model. But various experimental properties, such as the short-lived ground state, are better described by an $\alpha$-clustering model. The B(E2) values of the decays of low-lying yrast states are an important fingerprint to...
The high-precision fast-timing method has been used in a high-statistics experiment at ALTO@IJCLab to perform lifetime measurements of excited states in exotic nuclei. These observables and their corresponding transition probabilities are key fingerprints for the structure of atomic nuclei, as they are sensitive to small components of the wave function. Neutron-rich nuclei have been populated...
The subject of this presentation is a measurement of internal conversion electrons aimed to study the structure of the low-lying states in $^{74}$Se.
Electric monopole (E0) transitions are determined by a change in the radial distribution of the electric charge inside the nucleus, and high E0 transition strengths are expected whenever configurations with different mean-square charge radii...
Lifetimes of nuclear excited states are key observables to study nuclear structure properties, such as the interplay between single-particle and collective degrees of freedom and more complex phenomena as the coexistence of different shapes at similar excitation energies. In this context, neutron-rich nuclei are particularly challenging and neutron-induced fission experiments offer a unique...
