1. The slow procee which is considered to have produced roughly a half of heavy elements in the Universe needs a certain amount of steady neutron flux in some stellar site. These neutrons are believed to be produced by the C13(a,n) reaction, but the cross section has been better estimated by a new expeeriment, giving roughly a half of neutron flux. This brings the conventiona s-process model difficult, and require significant chang in the modeling. (Phys. Rev. Lett. 2003)
2. Some new proton resonances were discovered that would incluence on the production rate of Mg22 in novae. This was a part of collaboration work with the TRIUMF (Canada) group. （Euro. Phys. J. 2002）
3. The production rate of Mg22 through the Na21(p,g) reaction was directly determined using the Na21 beam at TRIUMF. This was also a part of collaboration work with the TRIUMF (Canada) group. （Phys. Rev. Lett. 2003）
4. C11(p,g) stellar reaction, which should be critical for the evolution of the first generation stars, were investigated using the C11 beam from CRIB, the CNS low energy RI beam separator. (Phys. Lett. 2003)
5. The nuclear structure of N11, that locates outside of the drip line, is of great interest. It was studied by the (He3,He6) direct reaction. Several spin-parity assignments were made for new states. (Phys. Rev. C, 2003)
