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…
Energy of the Th Nuclear Clock Isomer Determined by Absolute -ray Energy Difference
A. Yamaguchi, H. Muramatsu, T. Hayashi +10
The low-lying isomeric state of Th provides unique opportunities for high-resolution laser spectroscopy of the atomic nucleus. We determine the energy of this isomeric stat…
Narrow-line Cooling and Determination of Magic Wavelength of Cd
A. Yamaguchi, M. S. Safronova, K. Gibble +1
We experimentally and theoretically determine the magic wavelength of the (5)(55) clock transition of Cd to be 419.88(14) nm and 420.1(7…
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…
Nuclear resonant scattering experiment with fast time response: new scheme for observation of Th radiative decay
A. Yoshimi, H. Hara, T. Hiraki +24
Nuclear resonant excitation of the 29.19-keV level in Th with high-brilliance synchrotron- radiation and detection of its decay signal, are proposed with the aim of populat…
