New estimate for the time-dependent thermal nucleosynthesis of Ta
T. Hayakawa, T. Kajino, S. Chiba +1
We have made a new time-dependent calculation of the supernova production ratio of the long-lived isomeric state of Ta. Such a time-dependent solution is crucial for unders…
Quantum Statistical Corrections to Astrophysical Photodisintegration Rates
G. J. Mathews, Yamac Pehlivan, Toshitaka Kajino +2
Tabulated rates for astrophysical photodisintegration reactions make use of Boltzmann statistics for the photons involved as well as the interacting nuclei. Here we derive analytic…
30S(alpha,p) in X-Ray Bursts at CRIB
D. Kahl, A. A. Chen, S. Kubono +13
Over the past three years, we have worked on developing a well-characterized 30S radioactive beam to be used in a future experiment aiming to directly measure the 30S(alpha,p) stel…
Neutrino reactions via neutral and charged current by Quasi-particle Random Phase Approximation(QRPA)
Myung-Ki Cheoun, Eunja Ha, K. S. Kim +1
We developed the quasi-particle random phase approximation (QRPA) for the neutrino scattering off even-even nuclei via neutral current (NC) and charged cur- rent (CC). The QRPA has…
Neutrino reactions on La and Ta via charged and neutral currents by the Quasi-particle Random Phase Approximation (QRPA)
Myung-Ki Cheoun, Eunja Ha, T. Hayakawa +2
Cosmological origins of the two heaviest odd-odd nuclei, La and Ta, are believed to be closely related to the neutrino-process. We investigate in detail neutrino-in…
Asymmetric Neutrino Emission from Magnetized Proto-Neutron Star Matter including Hyperons in Relativistic Mean Field Theory
Tomoyuki Maruyama, Toshitaka Kajino, Nobutoshi Yasutake +2
We calculate asymmetric neutrino absorption and scattering cross sections on hot and dense magnetized neutron-star matter including hyperons in fully relativistic mean field theory…
