Exploration for Astromers near Sn with the Canadian Penning Trap
A. A. Valverde, S. Cupp, A. Gross +26
Nuclear isomers can have significant impacts on astrophysical nucleosynthesis processes, with recent efforts demonstrating that the population of isomeric states with different hal…
Offline Commissioning of the St. Benedict Gas Catcher
F. Rivero, D. Guillet, M. Brodeur +11
Precision measurements of decay transitions offer a promising channel through which the Standard Model (SM) can be probed. There is currently an ongoing effort to increase the…
Precision Mass Measurements of \textsuperscript{130}Te, \textsuperscript{130}Sn, and Their Impact on Models for R-Process Nucleosynthesis
A. Cannon, W. S. Porter, A. A. Valverde +12
The astrophysical rapid neutron capture nucleosynthesis process (r-process) remains an active area of research due to the fact that it occurs in extreme conditions and involves rea…
Precise Mass Measurement of the La-Ce-Pr isobaric chain
B. Liu, M. Brodeur, J. A. Clark +13
Penning trap mass measurements of La, Ce, and Pr were performed with the Canadian Penning Trap (CPT) at the CARIBU facility of Argonne National Laboratory u…
Off-line Commissioning of the St. Benedict Radiofrequency Quadrupole Cooler-Buncher
D. P. Burdette, R. Zite, M. Brodeur +20
The St. Benedict ion trapping system, which aims to measure the angular correlation parameter in superallowed-mixed mirror transitions, is under construction at the Univers…
Astrophysical significance of the isomer Ag demonstrated through direct mass measurement
F. Rivero, M. Brodeur, J. A. Clark +18
The abundance of elements heavier than iron produced via the astrophysical rapid-neutron capture process depends sensitively on the atomic mass of the involved nuclei as well as th…
