A measurement was recently performed at the National Superconducting Cyclotron Laboratory on resonant proton scattering of 46Ar in inverse kinematics in the region of isobaric analog states of 47Ar. The experiment was performed using a re-accelerated 46Ar radioactive beam at 4.6 MeV/u from the ReA3 linac after production via the projectile fragmentation of a 48Ca primary beam from the Coupled...
Production of neutron-rich nuclei through one-nucleon knockout (p,2p) reactions has been successfully demonstrated with the MINOS at RIBF. In future RIBF experiments, a method to remove more than one protons with a reasonable rate will be required for production of more neutron-rich nuclei. At present there is no consensus on what is the best reaction for two-proton removal. In this...
Charge-exchange (CE) reactions at intermediary energies serve as a direct method for the extraction of the Gamow-Teller (GT) transition strengths, which are of importance for the estimation of weak-reaction rates for a variety of astrophysical phenomena such as core-collapse supernovae (CCSN) and the crustal heating of neutron
stars. In particular, CE reactions in the $\beta^+$...
A new beam line named OEDO which can degrade the beam energy and squeeze the spatial distribution was installed at RIBF. As the first campaign of the experiments, $^{77,79}$Se(d,p)$^{X}$Se reactions were measured as a surrogate of the $^{79}$Se($n, \gamma$)$^{80}$Se* reaction for the nuclear mutation of the radioactive waste of $^{79}$Se. The $\gamma$ transition probabilities from the unbound...
The Beijing Radioactive Ion-beam Facility (BRIF) is a large-scale scientific infrastructure, which was commissioned as the national first RIB facility based on the Isotope Separator On Line (ISOL) technique in October, 2016. BRIF is comprised of a high-intensity proton cyclotron, thick-target and ion source system, isotope separator on line and the HI-13 tandem as the post accelerator. The...
