The recent discovery of the low-energy enhancement in the photon strength function (PSF) of medium mass nuclei in the Fe and Mo region [1] has attracted great experimental and theoretical attention, as it may represent a new decay-mode [2]. The presence of an enhanced decay probability of low-energy gammas rays below the neutron threshold has the potential to greatly affect a broad range of...

An RF-only ion funnel has been developed to efficiently extract single Ba ions from a high-pressure (10 bar) xenon gas into vacuum. Gas is injected into the funnel where ions are radially confined by an RF field while the neutral gas escapes. Residual gas flow alone (without any DC drag potential) transports the ions longitudinally through the funnel. In the downstream chamber the ions are...

Nuclei far from stability with a large imbalance between the number of protons and neutrons exhibit characteristic decay modes which are still far from being fully explored, both experimentally and theoretically [1]. One of them is emission of beta-delayed charged particles, which occurs for nuclei close to the proton drip-line. In addition to single (beta p) and double (beta 2p) delayed...

Nuclei beyond the proton drip line have been intensively investigated in recent years, and their structure exhibited exotic features that cannot be found in particle-stable nuclei. For instance, two-proton (2p) radioactivity of elements was discovered on 45Fe. In spite of the experimental advances, most 2p-decay precursors remain unexploited though their low-excitation spectrum is expected...

The N = 40 subshell closure, which arises from the energy separation of the νpf shell and the νg9/2 single-particle state, has long been investigated for its impact on nearby neutron-rich nuclei. The fragility of this N = 40 subshell closure is highlighted by the sudden onset of collectivity as protons are removed from the νf7/2 single-particle state. Cross-shell excitations have been used to...

The coexistence of normal and intruder nuclear states close in energy is a characteristic feature of nuclear structure [1]. The lowering in energy of states originating from excitations across the shell closures is a delicate balance between the energy cost to break the shell gap, and the gain in pairing and quadrupole energy. A region of great interest for these studies is the N = 50 isotonic...

Particle-bound isotopes along the neutron dripline have been searched for fluorine (Z = 9) and neon (Z = 10) isotopes at the RIKEN RI Beam Factory (RIBF) by using projectile fragmentation of an intense 48Ca beam at 345 MeV/nucleon and the large-acceptance fragment separator BigRIPS. Observation of null counts for 32F, 33F and 35Ne, 36Ne isotopes and comparison with their expected production...

The Atomic Mass Evaluation (AME) has been serving the research community with the most reliable source for comprehensive information related to the atomic masses since 1950s. It provides the best values for the atomic masses and their associated uncertainties by evaluating all available experimental data from nuclear reactions, radioactive decays and direct mass measurements using a weighted,...
