Estimation of radiative half-life of Th by half-life measurement of other nuclear excited states in Th
Y. Shigekawa, A. Yamaguchi, K. Suzuki +8
We perform coincidence measurements between particles and rays from a U source to determine the half-lives of the excited state in a Th nucleus. We first pr…
Absolute X-ray energy measurement using a high-accuracy angle encoder
Takahiko Masuda, Tsukasa Watanabe, Kjeld Beeks +16
This paper presents an absolute X-ray photon energy measurement method that uses a Bond diffractometer. The proposed system enables the prompt and rapid in-situ measurement of phot…
X-ray pumping of the Th-229 nuclear clock isomer
Takahiko Masuda, Akihiro Yoshimi, Akira Fujieda +27
Thorium-229 is a unique case in nuclear physics: it presents a metastable first excited state Th-229m, just a few electronvolts above the nuclear ground state. This so-called isome…
Towards an energy measurement of the internal conversion electron in the de-excitation of the Th-229 isomer
Simon Stellmer, Yudai Shigekawa, Veronika Rosecker +5
The first excited isomeric state of Th-229 has an exceptionally low energy of only a few eV and could form the gateway to high-precision laser spectroscopy of nuclei. The excitatio…
