Sub-Doppler cooling in a compact conical hollow mirror integrated with anti-Helmholtz coils
Shintaro Nagase, Naoya Ozawa, Teruhito Nakashita +7
We demonstrate sub-Doppler cooling of rubidium (Rb) atoms using a compact, single-beam configuration based on a conical hollow mirror integrated with anti-Helmholtz coils. T…
Production and chemical separation of Pa toward observation of rays of Th
Yudai Shigekawa, Xiaojie Yin, Akihiro Nambu +2
To observe the rays emitted from the low-lying isomeric state of Th (Th), we aim to dope fluoride crystals with its precursor Pa. In this study, w…
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…
Activation cross sections of α-induced reactions on Zn for Ge and Ga production
Masayuki Aikawa, Moemi Saito, Shuichiro Ebata +2
The production cross sections of Ge and Ga by α-induced reactions on Zn have been measured using the stacked-foil activation method and off-line γ-ray s…
Cross section measurement of alpha particle induced nuclear reactions on natural cadmium up to 52 MeV
F. Ditrói, S. Takács, H. Haba +2
Cross sections of alpha particle induced nuclear reactions have been measured on thin natural cadmium targets foils in the energy range from 11 to 51.2 MeV. This work was a part of…
Excitation function of the alpha particle induced nuclear reactions on enriched Cd, production of the theranostic isotope Sn
F. Ditrói, S. Takács, H. Haba +4
Sn is one of the radioisotopes can be beneficially produced through alpha particle irradiation. The targets were prepared by deposition of Cd metal onto high purit…
First Online Mass Measurements of Isobar Chains via Multi-Reflection Time-of-Flight Mass Spectrograph Coupled with GARIS-II
P. Schury, M. Wada, Y. Ito +16
Using a mulit-reflection time-of-flight mass spectrograph (MRTOF-MS) located after a gas cell coupled with the gas-filled recoil ion separator GARIS-II, the masses of several heavy…
New Result in the Production and Decay of an Isotope, 278[113], of the 113th Element
Kosuke Morita, Kouji Morimoto, Daiya Kaji +35
An isotope of the 113th element, i.e., 278[113], was produced in a nuclear reaction with a 70Zn beam on a 209Bi target. We observed six consecutive α-decays following the implantat…
Decay Properties of Bh and Db Produced in the Cm + Na Reaction
K. Morita, K. Morimoto, D. Kaji +21
Decay properties of an isotope Bh and its daughter nucleus Db produced by the Cm(Na, 5\textit{n}) reaction were studied by using a gas-filled recoil…
