When muons are injected into a deuterium thin film target, muon molecules are formed. The muons released after intramolecular fusion (recycling muons) are important for the development of slow muon beams. In this study, corresponding to an experiment in which recycling muons are transported using a coaxial transport tube, the energy distribution of scattered muons, muons after deceleration, and background radiation due to bremsstrahlung by decay electrons and neutrons are analyzed by numerical simulations.

When swift heavy ions are irradiated to ceramics, ion track damage is often created. The core-shell structure of ion tracks has been reported for amorphous SiO
irradiated with the swift heavy ions. In the present study, we succeeded in observing the core-shell structure of crystalline SiO. The formation mechanism of the core-shell structure is discussed.

For a paramagnetic superconductor UTe, a "field-reionforced superconducting state" in which 
increases with magnetic field above 15 T emerges when a magnetic field is applied "exactly" in the direction of the magnetically hard 
axis. In order to investigate this high-field superconducting phase, we have attempted to determine the magnetic field-temperature phase diagram of ultra-clean single crystals using a cryogen-free 25 T superconducting magnet (25T-CSM) at the High Field Laboratory for Superconducting Materials, Institute for Materials Research, Tohoku University. In this presentation, we will report the obtained results.

The J-KAREN-P laser at the Kansai Photon Science Institute was irradiated to a cluster target and confirmed the second harmonic generation. Polarization measurements of the generated second harmonic revealed that the polarization plane of the component that passed through the laser-generated plasma was rotated. This result suggests that a vortex-like magnetic field centered on the laser axis is generated.

In recent years, due to advances in precision measurement technology in pulsed magnetic fields, a novel magnetic state was discovered in a strong magnetic field. We constructed a measurement environment that can comprehensively explore the reciprocal lattice space under magnetic fields up to 14 Tesla by combining the long-pulse magnetic field generated by the supercapacitor and pulsed neutrons at J-PARC. This equipment can generate a magnetic field that is sufficiently longer than the time width (about 10 milliseconds) of the multi-wavelength neutron pulse passing through the sample. This method was used to investigate the magnetic phase transition in the frustrated magnet CuFeO.

In this talk, I will introduce a recent paper which received the young scientist award of the physical society of Japan, 2023. The alpha knockout reaction has been used as a probe for the alpha clustering in light nuclei. In this paper, I applied the alpha knockout reaction to the alpha-decay nuclei. Due to the strong absorption effect of the alpha particle, the alpha knockout cross section has high sensitivity to the alpha amplitude on the nuclear surface. The alpha reduced width, which is equivalent to the surface alpha amplitude, is also a key quantity of the alpha decay phenomena. Therefore we can expect a strong relation between the alpha knockout cross section and the alpha reduced width. In this paper, I theoretically showed that there is a clear relation between the cross section and the reduced width, and hence the alpha knockout reaction is a new probe for the alpha reduced width.
