$$\beta $$ -detected nuclear magnetic resonance ( -NMR) is a powerful research tool in physics and material sciences. In this study, we integrated an imaging function into -NMR instrument. Specifically, installed position-sensitive detectors to create device, which have named the -MRI. We conducted experiments evaluate performance of device by irradiating spin-polarized $$^{12}$$ B beams on sample, successfully generated its mapping image.
Muon spin relaxation/rotation/resonance ( $$\varvec{\mu \textrm{SR}}$$ ) method is one of the most effective experimental methods and has been used in many fields such as material science, chemical, bioscience since 1970s. For next elevation , we developed positron detectors that have a spatial resolution them trackers so could construct an image sample. Demonstrative experiments were performed at TRIUMF sample was successfully reconstructed.
The muon spin rotation/relaxation/resonance ( $$\varvec{\mu }$$ SR) spectroscopy is widely used as a unique tool for probing magnetic properties in materials. We aim to enhance this method by incorporating imaging functionality. In study, we conducted an experiment using new device that utilizes positron tracking from decays assess the reliability of and its positional resolution. As result, have demonstrated image depicting hole with diameter 5 mm could be reconstructed.
Charge-changing cross sections $${\sigma _{cc}}$$ for mirror nuclei pair, $$^{22}$$ Ne and Mg, on carbon proton targets were measured at 120 MeV/nucleon. The experimental _{cc}^{exp.}}$$ compared with Glauber-type calculations using the known density distribution of target projectile. Moreover, assuming perfect charge symmetry, radius Mg was deduced that from isotope shift. We examined possibility charge-changing section as a new method to determine neutron skin thickness.
Nuclear magnetic resonance (NMR) using β-decay radioisotopes, known as “β-NMR,” is used for research in nuclear physics. Recently, moments of radioisotopes have been precisely measured by β-NMR. Therefore, can be NMR spectroscopy material sciences. Nuclei, whose spin zero, such 12C and 16O, cannot conventional NMR. However, nonzero-spin radioactive isotopes carbon oxygen This advantage powerful investigating organic materials that investigated A technique being developed to extend β-NMR...
