We are developing a single-channel readout from the cathode planes of a multi wire drift chamber to achieve both self triggering and high tracking efficiency in 6He beam experiments at CRIB.
In this report, charge exchange reaction of rubidium and francium ions using an yttrium neutralizer is discussed.
We will report the current status of the development of emittance monitor for high-intensity beam accelerated by AVF Cyclotron.
In Autumn 2017, the OEDO setup was commissioned during a series of day 0 experiments performed by the ImPACT 17-02-01 collaboration. One of these experiments measured $^{93}$Zr+d transmutation reactions at ~ 28 MeV/u, the lowest energy to date. Deuterons have a low binding energy (2.224 MeV) and therefore undergo breakup whilst in the presence of Coulomb and nuclear fields. By comparing...
The Dielectron production in central PbPb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV is disscused.
The two-proton radioactivity (2p decay) is an exotic decay mode that was predicted theoretically in the 1960s and first discovered experimentally in 2002. Two protons are simultaneously emitted from the ground state of some neutron-deficient nuclei such as 19Mg, 45Fe, 48Ni, and 54Zn.
Because the two-proton emitters are very undatable, it is difficult to study their energy structure, and the...
In the X-ray bursts, the ${}^{26}$Si($\alpha$, p)${}^{29}$P reaction rate has a great impact on the light curve. However, there was not enough experimental data for this reaction because of the technical difficulty.
A direct measurement was performed at the CNS RI beam separator (CRIB). And the yield of the ($\alpha$,p) reaction was determined by removing the background events seen in the...
Recent sensitivity studies showed that the $^{14}$O($\alpha,p$)$^{17}$F is one of the very important reactions affecting a large uncertainty of energy generation and final ash in X-ray burst models. The reaction was also emphasized as a key determination of the break-out path from the hot CNO cycle to the $rp$-process at sufficiently high temperatures (T$_{9}$ > 0.5), specifically the spin and...
We did the experiment that carried out mass measurements around 47Fe in May 2022. Then, we made a lot of unstable nuclei. Some of them emitted γ-rays and backed to ground state. These γ-rays measured by Ge detector. In this experiment, we succeeded in measuring the half-life of the 107-keV isomeric state in 45Cr.
We performed a missing mass spectroscopy at RIBF using double charge exchange reaction $^{48}$Ca($^{12}$C, $^{12}$Be(0$^{+}_{2}$)), aiming for the observation of the double Gamow-Teller giant resonance. We observed some structures in the excitation energy spectrum of $^{48}$Ti at the energy region where the double Gamow-Teller giant resonance is expected to exist. We compared the experimental...
The heavy-ion fusion reaction is powerful in expanding the chart of nuclides as well as exploring the nuclear structure beyond Pb (Z = 82). A fusion experiment was performed at HIMAC to study the inverse kinematic systems by bombarding the low-energy $^{136}$Xe beam onto $^{27}$Al, $^{nat}$Cu and $^{nat}$Zn targets. Two newly developed detectors were used in the experiment: a...

In this report, we report multiplicity dependence of direct photon production in pp collisions at $\sqrt{s}$ = 13 TeV. The purpose of this study is to investigate if thermalized system such as the quark-gluon plasma (QGP) is created even in the small colliding system.
The Machine study for the 6He+p experiment was carried out in CRIB, the 6He beam energy was ~48 MeV with 91% purity via 20 um mylar degrader. We also carried out one short scattering measurement of the 6He+p reaction with one set of dE-E detectors, the locus of the p, d, t, alpha, 6He can be clearly seen. The proton and triton were identified combined with the kinematic calculation of the...
We briefly report the OEDO-SHARAQ experiments performed in FY2022.

In this report, we report dielectron measurement capabilities in the phase 3 upgrade of the LHC-ALICE experiment.
The purpose of this study is to evaluate whether the electrons from the pre-equilibrium process can be measured using electron identification by ECal.
The current status of studies on the ALICE-TPC space-charge distortion correction using machine learning methods will be discussed in this article.
130Sn(d,p) reaction in the inverse kinematics was measured at OEDO/SHARAQ beam line to deduce the neuron capture reaction rate of 130Sn. The energy degraded 130Sn, 130Te, and 124Sn beams were directed onto a thin CD2 target. The reaction residues were identified by the SHARAQ in coincidence with the recoild protons detected by TiNA2 array.
