Establishing the Ca reaction at 392 MeV under quasi-free scattering conditions
Riku Matsumura, Junki Tanaka, Kazuki Yoshida +80
The reaction offers a direct means to probe preformed -cluster structures in nuclei under quasi-free scattering conditions. Previous studies around 100 MeV provided va…

Xenon-gas ionization chamber to improve particle identification of heavy ion beams with Z>70
Masahiro Yoshimoto, Naoki Fukuda, Riku Matsumura +9
In conventional ionization chambers (ICs) using P-10 (Ar+CH4) gas, as the atomic number (Z) of the ion beams increases in the energy region of 200-300 MeV/u, the Z resolution deter…
