Decay Q-values are necessary to calculate the phase-space factors which determine the decay rates of double beta and double electron-capture decays. Precision measurements of the masses of these isotopes unambiguously determine their Q-values, and this work discusses the result of a Penning trap mass measurement obtained for a double electron-capture candidate using the Phase-Imaging...
The breakup of weakly bound nuclei is a key probe of nuclear structure at the limits of stability. In this work, we investigate the breakup of the one-neutron halo nucleus 19C on a lead target at 69AMeV using the Coulomb-Corrected Eikonal approximation (CCE). To rigorously quantify uncertainties and constrain model parameters, we employ a Bayesian analysis framework for the description of 19C,...
Standard hadrons are composed of either a quark-antiquark pair or three quarks, with their properties accurately described by the quark model. However, ”exotic” hadrons, containing more than three quarks or including gluons, are also theorized. The 2003 discovery of the X(3873) by the Belle collaboration, a four-quark state with unexpected properties, sparked intense interest in these exotic...
Channel coupling plays a crucial role in enhancing sub-barrier fusion in heavy-ion collisions by splitting a single potential barrier into a measurable barrier distribution (BD). Heavy- ion reactions near the Coulomb barrier are particularly sensitive to these coupling effects, making them ideal for investigating the interplay between the relative motion of nuclei and their intrinsic degrees...
In xenon-based rare-event search experiments in underground laboratories, radioactive noble gases dissolved in the xenon, in particular 222Rn and its betta-emitting decay products, have become a dominant internal background source. This contribution will present methods for the continuous active removal of radon from xenon, using cryogenic online distillation as implemented in current setups...
