We measured the invariant mass of the η^{'}(958) meson through the η^{'}→γγ decay channel to search for possible character change of η^{'} in a nuclear medium. The measured invariant-mass spectra were analyzed by fitting realistic spectral functions. An enhancement was observed in …

The ground-state rotational band of ^{252}Fm (Z=100, N=152) was investigated using two different experimental setups at the JAEA Tandem Accelerator Laboratory. The 2^{+}→0^{+} and 4^{+}→2^{+} transitions were observed in the α decay of ^{256}No via α-γ coincidence spectroscopy. The energies of the …

For the spectroscopy of nucleon resonances at the total energies from the $η^\prime$-meson production threshold to $2.32$ $\mathrm{GeV}$, photon beam asymmetries of the reaction $γp \to η^\prime p$ were measured together with total and differential cross sections by analyzing the two decay …
