- Reiner Kruecken (TRIUMF)
The astrophysical rapid neutron capture process (r-process) is thought to be responsible for the production of roughly half of the heavy elements found in nature. At present the site and many other details of this process remain uncertain, making the detailed understanding of the r-process one of the most active areas of research in nuclear astrophysics. Testing the models describing the...
The Gamma-Ray Infrastructure For Fundamental Investigations of Nuclei (GRIFFIN) is a new state-of-the-art gamma-ray spectrometer. GRIFFIN is composed of 64 large-volume high-purity germanium detectors arranged in 16 clovers and is designed to measure the decay of radioactive-isotopes beams produced by the TRIUMF Isotope Separator and Accelerator (ISAC). The array can be coupled to a variety of...
The Electromagnetic Mass Analyzer, EMMA, is a recoil mass spectrometer installed at the ISAC-II facility of TRIUMF. It is designed to spatially separate the recoils of nuclear reactions from the beams that induce them and to disperse the products in a focal plane according to their mass-to-charge ratios. A first test of the spectrometer was carried out in December 2016 in which an 80 MeV...
Nuclei around doubly magic $^{132}$Sn are of particular interest in terms nuclear structure as well as nuclear astrophysics. The properties of these nuclei provide important input parameters for the astrophysical $r$-process (rapid neutron-capture process) since they play an role as waiting-point nuclei and their shell structure and half-lives affect the shape of the second $r$-abundance peak....
The $^{22}$Ne(p,$\gamma$)$^{23}$Na reaction largely impacts the abundance of the only stable sodium isotope, $^{23}$Na, in various stellar environments, such as AGB stars, massive enough to undergo hot-bottom burning, type Ia supernovae and novae. However, the $^{22}$Ne(p,$\gamma$)$^{23}$Na reaction rate still carries one of the highest uncertainties among the astrophysical reactions...
