Measurement of production branching ratio after muon nuclear capture reaction of Al and Si isotopes

R. Mizuno, M. Niikura, T. Y. Saito +18

Background: Muon nuclear capture is a reaction between a muon and a proton inside a nucleus through weak interactions. This reaction results in the formation of an excited nucleus,…

Measurement of the mesonic decay branch of the quasi-bound state

T. Yamaga, S. Ajimura, H. Asano +67

We conducted measurements of reactions using a -beam, with the objective of understanding the broad decay width of $\bar…

Ordinary muon capture rates on Mo and Mo for astro-antineutrinos and double beta decays

I. H. Hashim, H. Ejiri, N. N. A. M. A. Ghani +12

\item[Background] The nuclear responses for antineutrinos associated with double beta decays (DBDs) and astro-antineutrino interactions are studied by measuring ordinary muon captu…

Muonic X-Ray Measurement for the Nuclear Charge Distribution: the Case of Stable Palladium Isotopes

T. Y. Saito, M. Niikura, T. Matsuzaki +16

Background: The nuclear charge radius and distribution are the most fundamental quantities of the atomic nucleus. From the muonic transition energies, the absolute charge radius ha…

Development of microwave cavities for measurement of muonium hyperfine structure at J-PARC

K. S. Tanaka, M. Iwasaki, O. Kamigaito +16

The MuSEUM collaboration is planning measurements of the ground-state hyperfine structure (HFS) of muonium at the Japan Proton Accelerator Research Complex (J-PARC), Materials and…
