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…
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…
Evolution of chirality from transverse wobbling in Pr
N. Sensharma, U. Garg, Q. B. Chen +20
Chirality is a distinct signature that characterizes triaxial shapes in nuclei. We report the first observation of chirality in the nucleus Pr using a high-statistics Gamma…
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…
Al Half-life Measurement and the negative mirror asymmetry between the Al($β^-$)Si and P($β^+$)Si decays
B. Liu, M. Brodeur, D. W. Bardayan +12
In the past, the mirror asymmetry parameter has been proposed as a probing mechanism for the presence of beyond the Standard Model second-class currents in nuclear beta decay trans…
