1557. The determination of the masses of neutron-rich nuclides using the CPT mass spectrometer at CARIBU

Dr Kumar Sharma (University of Manitoba)

Nuclear Physics / Physique nucléaire (DNP-DPN)

Invited Speaker / Conférencier invité

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...

1561. Recent Results in Decay Spectroscopy with GRIFFIN

Invited Speaker / Conférencier invité

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...

1599. Initial Tests of the Recoil Mass Spectrometer EMMA

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...

1632. Decay Spectroscopy of Neutron-rich ${}^{129}$Cd with GRIFFIN

Mr Yukiya Saito (The University of British Columbia / TRIUMF)

Nuclear Physics / Physique nucléaire (DNP-DPN)

CLOSED - Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)

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....

1833. WITHDRAWN - Direct study of the ${}^{22}$Ne(*p,$\gamma$*)${}^{23}$Na reaction in inverse kinematics using the DRAGON recoil separator

Nuclear Physics / Physique nucléaire (DNP-DPN)

CLOSED - Oral (Non-Student) / orale (non-étudiant)

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...
