Characterization of the GARIS-III Separator via the 40 Ar + 208 Pb Fusion Evaporation Reaction

This work reports on the measurements performed during the commissioning of the GARIS-III separator in RIKEN with the study of the 40 Ar + 208 Pb → 248 Fm * reaction. The excitation functions of the 2n, 3n, and 4n exit channels were measured with maximum cross sections of 27.5 ±...

Concurrence in Neutron–Proton Scattering for Polarization-Induced Mixed States

We investigate spin entanglement generated in neutron–proton scattering by evaluating the concurrence from the scattered two-nucleon density matrix. While previous studies mainly discussed pure initial spin states, the present work extends the analysis to polarization-induced mix...
