Metal-poor stars in the Galactic halo have been studied for the past half century in order to understand the chemical evolution of the Galaxy, extending back to the first generations of stars born in the Universe. However, only within the last twenty years have very metal-poor, highly r-process-element-enhanced (r-II) stars begun to shed light on the cosmic origin of the r-process elements....

The neutrinos that emerge in the core collapse supernovas play an important role in the cooling mechanism of the proto-neutron star (PNS). The luminosity of the neutrinos that emerge in the explosion is estimated to be 10^{52} erg/s [1]. Although the neutrinos’ interaction cross-section is relatively very small, such a dense medium makes it possible for the neutrinos to engage in...

We study scaling behavior of a chiral order parameter in the low density region, performing a simulation of two-flavor lattice QCD with improved Wilson quarks. It have been confirmed that the scaling behavior of the chiral order parameter defined by a Ward-Takahashi identity agrees with the scaling function of the three-dimensional O(4) spin model at zero chemical potential. We discuss the...

The activation technique is a widely used method for the determination of cross- section values for charged-particle induced reactions at astrophysically relevant energies. Since network calculations of nucleosynthesis processes often depend on reaction rates calculated in the scope of the Hauser-Feshbach-statistical model, these cross-sections can be used to improve the nuclear-physics...

Differential cross sections for elastic electron scattering reflect on charge distribution of nuclei because they are given by products of the Mott cross section and charge form factors. Charge distribution of nuclei is obtained from the Fourier transform of the charge form factors.
We conducted an experiment of electron scattering to study the relations between the cross section and the...

We study neutrino oscillations of reactor neutrinos, anti-electron neutrinos, both in the short- and medium- to long-baseline cases. THe survival and generation probabilities of the neutrinos are calculated within the three-flavor mixing model, and the dependence of the probabilities on the mass hierarchy and CP-phase is investigated. We find that the hierarchy can be determined from the...

We study neutrino oscillations of atomospheric neutrinos when they go through the earth, which has a dense core and a mantle with less density. Survival probabilities of atomospheric muon neutrinos are calculated within the three-flavor mixing model. Dependence of the probability at the exit surface of the earth on the neutrino energy and zenith angle is investigated. The survival probability...

The nuclear equation of state (EoS) is one of the most fundamental expressions that describe the basic relationship between energy, pressure, density, temperature, and isospin asymmetry δ=(ρ_n-ρ_p)/(ρ_n+ρ_p) for a nuclear system. For a neutron star, which has extreme asymmetry of its isospin, the symmetry energy term of the EoS is considered to play an important role in determining physical...

Recent experimental results have confirmed a possible reduction in the GT+ strengths of pf-shell nuclei. These proton-rich nuclei are of relevance in the deflagration and delayed-detonation and explosive burning phases of Type Ia supernovae (SNe Ia). While prior GT strengths result in nucleosynthesis predictions with a higher-than-expected neutron-excess isotopes for the elements...

We calculate the energy gap (latent heat) and pressure gap between the hot and cold phases of the SU(3) gauge theory at the first order deconfining phase transition point. We perform simulations around the phase transition point with the lattice size in the temporal direction Nt = 6; 8 and 12 and extrapolate the
results to the continuum limit. We also investigate the spatial volume...

We have studied nuclear reactions for Long-Lived-Fission-Products (LLFP) 90Sr for the purpose of nuclear transmutation. The nuclear data of proton and deuteron beam for LLFP target is one of the essential dataset for the study of transmutation. However, the nuclear data for those LLFP are insufficient and the accumulation of precise nuclear data is required. The interaction cross sections...

In couple of decades, thanks to the development of the radioactive isotope beam technology, the study for neutron-rich light nuclei has become possible. The nuclei in this region often have the exotic properties, such as the neutron halo, disappearance of the canonical magic numbers, and appearance of the new magic numbers.
Recently, in the experimental study of the neutron-rich nuclei[1],...

Low-lying (less than 1 MeV) resonances in neutron-rich nuclei has important role in neutron capture phenomena like the r-process. We focus on a new type resonance in superfluid nuclei. That is called quasi-particle resonance [1,2]. Many nuclei with open-shell configuration have superfluidity generated by pairing correlation. The pairing correlation causes continuum coupling in weakly bound...

The astrophysical rapid neutron capture process (r process) of nucleosynthesis is thought to be responsible for the production of roughly half of the elements heavier than iron. Despite its large influence in explaining the observed abundance of heavy elements, much of the r process is still poorly understood. A more thorough library of nuclear data, including masses, of neutron-rich nuclei is...

Core-collapse supernovae are the extremely energetic deaths of massive stars. As such, they play a vital role in the synthesis and dissemination of many heavy elements in the universe. In the past, core-collapse supernova nucleosynthesis calculations have relied on artificial explosion methods that do not adequately capture the physics of the innermost layers of the star. The PUSH method,...

Nuclear structure information serves as important inputs for the study of nuclear astrophysics, for example, the equation of state for neutron star, and the nuclear masses and decay rates for nucleosynthesis . Nowadays ab initio methods have been paid more and more attention since they study nuclear structure from the realistic nucleon-nucleon (NN) interaction, which can be obtained either...

Within the C/Ne convective shell of a massive star the 23Na(α,p)26Mg reaction is an important source of protons for 26Al production[1]. This shell is also the main source of Na ejected by core-collapse supernovae.

We study the transverse polarization of hyperons produced in the high-energy unpolarized proton-proton collision in the framework of the collinear factorization. To understand this phenomenon is one of the big challenges in high-energy hadron physics because it can’t occur in the conventional framework for high-energy inclusive reactions: parton model and perturbative QCD. However, using the...
