Work of numerous research groups has shown different
outcomes of studies of the transition from the
ferroelectric $\alpha$-phase to the high temperature $\beta
$-phase of the multiferroic, magnetoelectric perovskite
Bismuth Ferrite (BiFeO$_3$ or BFO). Using the perturbed
angular correlation (PAC) method with $^{111m}$Cd as the
probe nucleus, the $\alpha$ to $\beta$ phase transition...
The complete characterization of high-energy Radioactive Ion Beams delivered to experimental stations is essential to the analysis of the phenomenology studied. This includes insights at the purity of the beam as well as its geometrical properties in the transverse and longitudinal phase spaces. The difficulty resides in adapting experimental techniques to very low-intensity ion beams...
The gamma-MRI approach proposes to use spin-aligned long-lived nuclear states and to combine the detection of their asymmetric gamma-ray emission with spin manipulation as in Magnetic Resonance Imaging (MRI). It aims to pave the way to a new medical imaging modality capable of overcoming some of the limitations of existing imaging modalities (PET, SPECT, MRI): the low spatial resolution of the...
The Resonance Ionization Laser Ion Source (RILIS) today is a well-established technique for highly efficient and chemically selective radioactive ion beam production at the worldwide leading radioactive ion beam facilities such as CERN-ISOLDE [[1]]. Additionally, these laser ion sources allow for direct optical spectroscopy of exotic nuclei with sub ion-per-second production yields....
A theoretical and practical investigation into the relation of the applied waveform and frequency with beam transmission of the general purpose Radio-Frequency Quadrupole cooler and buncher (RFQcb) commonly used at ISOLDE and the Offline 2 facility. Beams of ions were transported through the RFQcb with frequencies ranging from 100 kHz to 1 MHz in 250 Hz steps to determine the stability of ...
