Production of new neutron-rich isotopes near the N=60 isotones Ge92 and As93 by in-flight fission of a 345 MeV/nucleon U238 beam

Y. Shimizu, T. Kubo, T. Sumikama, N. Fukuda et autres

A search for new neutron-rich isotopes near the $N=60$ isotones $^{92}\mathrm{Ge}$ and $^{93}\mathrm{As}$ has been performed using a 345 MeV/nucleon $^{238}\mathrm{U}$ beam at the RIKEN Nishina Center RI Beam Factory. Fission fragments produced were analyzed and identified in flight using the large-acceptance …

Demonstration of nuclear gamma-ray polarimetry based on a multi-layer CdTe Compton camera

S. Go, Y. Tsuzuki, Hiroki Yoneda, Y. Ichikawa et autres

To detect and track structural changes in atomic nuclei, the systematic study of nuclear levels with firm spin-parity assignments is important. While linear polarization measurements have been applied to determine the electromagnetic character of gamma-ray transitions, the applicable range is strongly limited …

Fundamental Study on Alkali-Activated Slag System with Sodium Carbonate or Calcium Hydroxide

Seunghyun Na, Wenyan Zhang, Y. Ichikawa, Masaya Komatsu et autres

Cement as a building material, has high fluidity, compressive strength, and durability, but carbon dioxide emissions during cement production are a major problem. As one of the countermeasures, alkali-activated cement using blast furnace slag powder with alkaline stimulants is considered to be …

Nuclear magnetic moment of the neutron-rich nucleus O21

Yuji Ishibashi, A. Gladkov, Y. Ichikawa, A. Takamine et autres

The ground-state magnetic dipole moment of the neutron-rich $^{21}\mathrm{O}$ isotope has been measured via $\ensuremath{\beta}$-ray-detected nuclear magnetic resonance ($\ensuremath{\beta}\text{\ensuremath{-}}\mathrm{NMR}$) spectroscopy by using a spin-polarized secondary beam of $^{21}\mathrm{O}$ produced from the $^{22}\mathrm{Ne}$ primary beam. From the present measurement, the $g$ factor $|{g}_{\mathrm{exp}}(^{21}\mathrm{O}_{\mathrm{g}.\mathrm{s}.})|=0.6036(14)$ …

Precise measurement of differential cross sections of the Σ-p --> Λ n reaction in momentum range 470-650 MeV/c

K. Miwa, Y. Akazawa, T. Aramaki, S. Ashikaga et autres

The differential cross sections of the Σ-p --> Λ n reaction were measured accurately for the Σ- momentum (p_{Σ}) ranging from 470 to 650 MeV/c at the J-PARC Hadron Experimental Facility. Precise angular information about the Σ-p --> Λ n reaction was …

Quantum sensing of the electron electric dipole moment using ultracold entangled Fr atoms

T. Aoki, B. K. Sahoo, Bindiya Arora, Takumi Sato et autres

Abstract We propose a method to measure the electron electric dipole moment (eEDM) using ultracold entangled francium (Fr) atoms trapped in an optical lattice, yielding an uncertainty below the standard quantum limit. Among the alkali atoms, Fr offers the largest enhancement factor …

Measurement of the differential cross sections of the Sigma-p elastic scattering in momentum range of 470 to 850 MeV/c

J-PARC E Collaboration, K. Miwa, J. K. Ahn, Y. Akazawa et autres

A high statistics $Σp$ scattering experiment has been performed at the J-PARC Hadron Experimental Facility. Data for momentum-tagged $Σ^{-}$ running in a liquid hydrogen target were accumulated by detecting the $π^{-}p \to K^{+}Σ^{-}$ reaction with a high intensity $π^{-}$ beam of 20 …
