- 中文摘要: 本文為研究質子對鍺七十核捕獲反應及砷七十一核能階,以i.o至2.5 MeV質子,鍺(鋰)探測器及特殊設計之靶室,進行70Ge(p,γ) 71 As核反應之實驗,測量當質子能量在2.434及2.030 MeV時之核反應所產生之伽瑪射線能階,從而得到原子核71lAs能階,其中發現八個新能階,有關核能階性質為自旋及宇稱等分別在文中討論之。
- 英文摘要: The 70Ge(p,γ) 7lAs reaction has been investigated in the energy rangefrom Ep=1.0 to 2.5 MeV. Excitation function was obtained for the reactionover this energy region. High-resolution measurements of the de-excitationγ-rays from this reaction have been made at Ep=2.434 and 2.030 MeV byusing a 50 cm3 Ge(Li)detector. The energy levels of 71As up to 2947 keVexcitation and γ-ray branching ratios were determined; several new levelsare proposed. The Q value for this reaction was also determined.
