64. Precision mass measurements for nuclear astrophysics

invited

Nuclear masses are key inputs for r-process calculations. With JYFLTRAP double
Penning trap at the IGISOL facility in the JYFL Accelerator Laboratory, we have recently
determined masses for dozens of neutron-rich nuclei and their isomeric states, see e.g.
[1-6]. With the phase-imaging ion-cyclotron resonance technique, it is possible to
resolve long-lived isomeric states with low...

The triple-alpha process is one of the most fundamental processes in stellar nucleosynthesis, entailing the fusion of three helium nuclei to form $^{12}$C. At temperatures between 0.1 - 2 GK, the triple-alpha reaction is almost exclusively mediated by the Hoyle state in $^{12}$C [1]. Accurate measurements of the radiative width of the Hoyle state is important for understanding the production...

4. The Pygmy Dipole Resonance and its evolution across the Sn mass region

Dr Maria Markova (University of Oslo)

invited

The pygmy dipole resonance (PDR) is commonly associated with excess $E1$ strength superimposed on the low-energy tail of the giant dipole resonance (GDR), near the neutron-separation energy in both stable and unstable heavy nuclei. Although its detailed structure, properties, and origin remain under debate, the neutron-skin oscillation picture still prevails, suggesting a dependence of the PDR...
