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…
Alpha-decay-correlated mass measurement of 206,207Ra using an -TOF detector equipped MRTOF-MS system
T. Niwase, M. Wada, P Schury +25
The atomic masses of the isotopes Ra have been measured via decay-correlated mass spectroscopy using a multi-reflection time-of-flight mass spectrograph equipped with a…
Investigation of alpha particle induced reactions on natural silver in the 40-50 MeV energy range
F. Ditrói, S. Takács, H. Haba +4
Natural silver targets have been irradiated by using a 50 MeV alpha-particle beam in order to measure the activation cross sections of radioisotopes in the 40-50 MeV energy range.…
Image reconstruction method for dual-isotope positron emission tomography
Tomonori Fukuchi, Mika Shigeta, Hiromitsu Haba +5
We developed a positron emission tomography (PET) system for multiple-isotope imaging. Our PET system, named multiple-isotope PET (MI-PET), can distinguish between different tracer…
Development of an "-ToF" detector for correlated measurement of atomic masses and decay properties
T. Niwase, M. Wada, P. Schury +12
We have developed a novel detector, referred to as an "-ToF detector", for correlated measurements of atomic masses and decay properties of low-yield, short-lived radioactive is…
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…
