Ground State Decay of the Three-Proton Emitter Na Reveals Isospin Symmetry Breaking
X. -D. Xu, I. Mukha, Z. C. Xu +24
The spectrum of the exotic three-proton (3p) emitter Na has been studied by detecting all in-flight decay products. Derived from the measured angular correlations O+p…
Excitation Spectra of the Reaction near the -Meson Emission Threshold Measured in Coincidence with High-Momentum Protons
R. Sekiya, K. Itahashi, Y. K. Tanaka +74
The missing mass of the reaction has been measured near the -meson emission threshold in coincidence with a high-momentum proton to selectively collect $…
Observation of Tensor-Driven High-Momentum Neutrons in O via () Reactions and Zero-Degree Deuteron Momentum Spectroscopy
X. Wang, H. J. Ong, S. Terashima +42
The reaction has been studied at using 403-, 604-, 907- and 1209-MeV protons, comparing cross sections populating positive- and ne…
Performance of newly constructed plastic scintillator barrel in the WASA-FRS experiments and evaluation of radiation damage effects on multi-pixel photon counter
Y. K. Tanaka, R. Sekiya, K. Itahashi +70
A barrel-shaped plastic scintillation counter with Multi-Pixel Photon Counter (MPPC) readout has been developed and operated in the first WASA-FRS experimental campaign at GSI. The…
Charge Pickup Reaction Cross Section for Neutron-Rich p-Shell Isotopes at 900A MeV
J. -C. Zhang, B. -H. Sun, I. Tanihata +34
We report charge pickup reaction cross sections for 24 \textit{p}-shell isotopes, including Li, Be, B, C and N, measured…
Half-life determination of heavy ions in a storage ring considering feeding and depleting background processes
R. J. Chen, G. Leckenby, R. S. Sidhu +49
Heavy-ion storage rings have relatively large momentum acceptance which allows for multiple ion species to circulate at the same time. This needs to be considered in radioactive de…
