The astrophysical rapid-neutron capture process (r-process) of explosive nucleosynthesis is responsible
for the formation of half of the heavy nuclei above Fe. Actinides are produced towards
the end of this process, when the neutron flux is expected to be minimal, and it is supported also
by fission processes. Given that the r-process path runs far away from the accessible species, in
this...
Spectroscopic properties of exotic nuclei are powerful tools to obtain a better insight on the evolution of nuclear structure far from the stability. Mid-shell nuclei are expected to exhibit collective behaviour which is typically reflected in the observation of low excitation energies of the first excited states and high transition probabilities. Moreover, the collectivity is expected to...
One of the best-known divergences from the independent-particle shell model description is the existence of islands of inversion [1]. The IoI of the region N=40 draws particular attention since the neutron number 40 was postulated as a non-traditional “magic” number and N = 40 represents the boundary between the negative-parity pf shell and the positive-parity g shell. In stable nuclei,...
In the past ten years, a series of experiments have been done at the HIRFL-RIBLL1 facility for studying the exotic decays of extremely proton-rich nuclei in sd-shell. Beta-delayed proton and two-proton decays from 20;21Mg, 22;23Al, 22;23;24Si, 26;27P, 27;28;29S have been measured by the continuous implantation-decay method using silicon array combined with gamma-ray detectors [1]. With high...
