Defect Dynamics and Isomer Quenching in Th:CaF Crystals
Ming Guan, Michael Bartokos, Kjeld Beeks +16
Thorium-229 doped calcium fluoride (Th:CaF) is a leading candidate for a solid-state nuclear clock, owing to the unusually low energy of the Th isomer transitio…
Nuclear Ptychoscopy: A Ptychographic Framework for Nuclear Spectroscopy
Ziyang Yuan, Yifei Zhang, Yonggong Teng +16
Accessing both amplitude and phase of nuclear response functions is central to fully characterizing light-matter interactions in the X-ray-nuclear regime. Recent work has demonstra…
X-ray-induced quenching of the Th clock isomer in CaF
Ming Guan, Michael Bartokos, Kjeld Beeks +27
Thorium-229 has the lowest nuclear-excited state (an isomer state) at approximately 8.356 eV, making it excitable with tabletop vacuum-ultraviolet lasers. Despite the recent succes…
Controlling Th isomeric state population in a VUV transparent crystal
Takahiro Hiraki, Koichi Okai, Michael Bartokos +27
The radioisotope Th-229 is renowned for its extraordinarily low-energy, long-lived nuclear first-excited state. This isomeric state can be excited by VUV lasers and the transition…
Fast X-ray detector system with simultaneous measurement of timing and energy for a single photon
T. Masuda, S. Okubo, H. Hara +12
We developed a fast X-ray detector system for nuclear resonant scattering (NRS) experiments. Our system employs silicon avalanche photo-diode (Si-APD) as a fast X-ray sensor. The s…
Electronic and Magnetic Phase Diagram of a Superconductor, SmFeAsO1-xFx
Yoichi Kamihara, Takatoshi Nomura, Masahiro Hirano +9
A crystallographic and magnetic phase diagram of SmFeAsO1-xFx is determined as a function of x in terms of temperature based on electrical transport and magnetization, synchrotron…
