Invited Speaker / Conférencier invité

The shape coexistence and shape transition at $N=60$ in the Sr, Zr region is the subject of substantial current experimental and theoretical effort. An important aspect in this context is the evolution of single particle structure for $N<60$ leading up to the shape transition region, which can be calculated with modern large scale shell model calculations using a ${}^{78}$Ni core or Beyond...

Along the $N=Z$ line, shell gaps open simultaneously for prolate and oblate deformations; the stability of these prolate and oblate configurations is enhanced by the coherent behaviour of protons and neutrons in $N=Z$ nuclei. Additionally, amplification of proton-neutron interactions along the $N=Z$ line may yield information on the isoscalar pairing interactions which have been predicted in...

Self-conjugate nuclei, where $N=Z$, exhibit a strong $pn$ interaction due to the large overlap of wavefunctions in identical orbitals. The heaviest $N=Z$ nuclei studied so far is ${}^{92}$Pd, and it has demonstrated a strong binding in the $T=0$ interaction [1]. As the mass number increases, the nucleus approaches the doubly-magic ${}^{100}$Sn. To investigate the evolution of the $pn$...

580. The Electromagnetic Mass Analyser EMMA

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

The Electromagnetic Mass Analyser EMMA is a recoil mass spectrometer for TRIUMF's ISAC-II facility designed to separate the recoils of nuclear reactions from the heavy ion beams that produce them and to disperse the recoils according to their mass/charge ratio. In this talk I will present an update on the construction and commissioning of the spectrometer and its components.

746. New decay modes of the high-spin isomer of ${}^{124}$Cs

As part of a broader program to study the evolution of collectivity in the even-even nuclei above tin, a series of $\beta$-decay measurements of the odd-odd Cs isotopes into the even-even Xe isotopes, specifically ${}^{122,124,126}$Xe, have been made utilizing the 8$\pi$ spectrometer at TRIUMF-ISAC. The 8$\pi$ spectrometer consisted of 20 Compton-suppressed high-purity germanium (HPGe) detectors...
