Takahiko Masuda, Sayuri Takatori,研究组得以分析所有位点的同质异能态寿命及激光诱导淬灭效应。
利用真空紫外激光探测掺入氟化钙(CaF2)晶体中钍-229(229Th)的低能核跃迁, 穆斯堡尔光谱学广泛应用于化学、地质学和固体物理学中,并识别出两种主要构型的微观结构, Thomas Riebner, Thomas LaGrange,结果发现了钍离子的四种不同掺杂位点, Felix Schneider,该技术为核环境探测提供了有力手段, Akihiro Yoshimi, Andreas Grneis, 研究组将该技术扩展至光学波段,这一研究成果于2026年8月20日发表在《科学》期刊上, Fabian Schaden,创刊于1880年, we extended this technique into the optical range using a vacuum ultraviolet laser to probe the low-energy nuclear transitions of thorium-229 (229Th) doped in calcium fluoride (CaF2) crystals. We discovered four distinct doping sites for the thorium ions,日本冈山大学Takahiro Hiraki团队研究了氟化钙中钍-229的激光穆斯堡尔谱学, Thorsten Schumm, Koji Yoshimura IssueVolume: 2026-08-20 Abstract: Mssbauer spectroscopy is widely used in chemistry。

and identified the microscopic structure of the two dominant configurations. Site-selective laser excitation enabled the study of the isomeric state lifetime and laser-induced quenching for all sites. This technique provides a powerful probe of the nuclear environment, Martin Pressler,用以探测材料中原子核的局域物理和化学环境, Georgy Kazakov,最新IF:63.714 官方网址: https://www.sciencemag.org/ 。
