Probing high-momentum components in O via zero-degree cross-section ratios

FRS Experiment Collaboration, X. Wang, H. J. Ong +40

The OO reaction was measured at zero degrees for incident-proton energies of 403, 604, 907 and 1209 MeV. Cross-section ratios for the 6.18-MeV (3/2) and 5.24…

Precision masses of neutron-rich platinum and gold nuclei reveal enhanced shell strength below doubly-magic Pb

David Freire-Fernández, Rui-Jiu Chen, Usama Ahmed +63

The heaviest stable nuclei in the universe owe their existence to quantum shell structure, the grouping of protons and neutrons into discrete energy levels separated by gaps. The l…

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 $η…

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…
