The availability of intense (>105 pps) beams of long-lived radioisotopes at energies just above the Coulomb barrier at the ReA facility at the National Superconducting Cyclotron Laboratory, and the newly implemented SOLARIS spectrometer led to a 2021 campaign of experiments to study varied aspects of nuclear structure in neutron-rich nuclei.
The N = 18 nucleus,...
Searching for superheavy elements (SHE) has been the subject of research for many years. At this time all discovered SHE were produced in the complete fusion reaction. It is expected that the cross-section for the new SHE production is on the order of tens of femto barns. That, together with technical barriers, like the need for high-intensity beams and suitably thick targets, creates a...
A program of study has been ongoing at Argonne National Laboratory to investigate
nuclei in the neutron-rich, rare-earth region through various experimental methods. The motivation of this work is to 1) deliver relevant information (masses and lifetimes) of isotopes that may help nuclear astrophysicists better understand the Rare-Earth Peak (REP) found in the mass abundance distribution and 2)...
