Nuclear Physics / Physique nucléaire (DNP-DPN)

Invited Speaker / Conférencier invité

Nuclei far from stability offer us the scope of exploring new features that surface prominently at large isospin and weak binding. This led to the discovery of the nuclear halo bringing a new era in nuclear science breaking the boundaries of conventional concepts. The halo properties elucidate new features that till date remain a challenge to decipher from fundamental principles. Defining...

The Xe isotopes are centrally located in the $Z>50$, $N<82$ region that displays an extraordinarily smooth evolution of simple collective signatures. However, the collectivity of excited states in this region is very poorly characterized because of a general lack of spectroscopic data for low-spin states that provide measures of collective properties such as relative and absolute...

1059. Doppler-shift lifetime measurements in $^{94}$Sr using the TIGRESS Integrated Plunger

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

Neutron-rich Sr isotopes are characterized by a sudden onset of quadrupole deformation at neutron number $N=60$ demonstrated by the dramatic drop in excitation energy of the first $2^+_1$ state. While theoretical calculations reproduce this onset of deformation qualitatively, they differ in the details of the deformation parameters and excitation energies. Though the emphasis is usually put on...

Electromagnetic transition rate measurements serve as a fundamental probe of nuclear structure and provide a stringent test for theoretical models. Doppler shift lifetime measurements offer an opportunity to directly access information about electromagnetic transition rates and discriminate between model calculations. The TIGRESS Integrated Plunger device (TIP), constructed at SFU, supports...

1303. Investigating the nuclear structure of 33Al through β− decay of 33Mg to probe the island of inversion

Spectra resulting from the decay reaction of 33Mg were captured using the GRIFFIN γ-ray spectrometer coupled with the SCEPTAR β particle detector at the Canadian laboratory, TRIUMF. A radioactive beam of approximately 104 counts per second of 33Mg was delivered by the Isotope Separator and Accelerator (ISAC) facility. In the past, nuclei away from the valley of stability were experimentally...
