Description

Accurate data of the photon-, alpha-, and neutron-induced reaction cross sections of a nucleus at astrophysics relevant energy are necessary to construct stellar models of nucleosynthetic yields of stars to trace the history of Galaxy. The cross section measurements of the 4He(γ, xnyp), 12C(4He, γ)16O, and 62Ni(n, γ)63Ni reactions were carried out using a quasi-monoenergetic pulsed photon beam with a newly developed 4π time projection chamber, a pulsed intense alpha beam with a newly installed high efficiency NaI(Tl) spectrometer, and a pulsed keV neutron beam with a high sensitive anti-Compton NaI(Tl) spectrometer, respectively. The present results were compared to previous data, recent theoretical calculations, and their astrophysics impacts were discussed. (author)
