SAMURAI International Collaboration Workshop 2017

Obtaining direct information on neutron-proton (np) correlations in nuclei is a long-sought goal in nuclear physics. Two-nucleon knockout reactions offer a powerful tool as the reaction cross section is a direct probe of nucleon correlations. The available experimental data with 12C incident on a C target at 1.05 and 2.10 GeV/u shows that the inclusive cross sections from np removal channel is...

We will report on the progress of the SAMURAI08 experiment. In this experiment, alpha-cluster levels in 16C were investigated with a 200 MeV/u 16C beam and a liquid He target. The four momenta of decay particles (alpha particle, neutrons and residuals) were measured by the SAMURAI spectrometer. The gamma-rays from the decay particles were also detected by DALI2. We will report the results of...

Neutron-neutron correlation in Borromean nuclei have been investigated by measuring the momentum distribution via the quasi-free (p,pn) reaction. We will report the result on 11Li.

The first kinematically complete measurement for the quasi-free (p,pn) reaction on Borromean nuclei 11Li, 14Be, and 17,19B was performed at RIBF in order to study dineutron correlation. Preliminary results on the dineutron correlation in 14Be and the spectroscopy of the unbound 13Be will be presented.
