• 中文摘要： 以-Ge (Li)偵測器與-Ge (Li) -Nal (Tl)偵測器構成符合系統之實驗方法研究Sb核吸收熱中子後形成Sb核並白貝他衰Te核能階間之伽瑪躍遷。測到共有38個伽瑪射線經以伽瑪射角度相關量度系統特別量取對1248.6ke V-602.6 keV-0，1325.6 keV-602.6 keV-0，2293.9 keV-602.6 keV-0，2693.8 keV-602.6 keV-0等串級躍遷之伽瑪射線，求出其能量，強度，多極混合比，研判 Te核能階至2.775 MeV。
• 英文摘要： The γ-radiation following the beta decay of 60.2d Sb from thermal neutron capture in Sb hasbeen investigated with a Ge(Li) detector and a Ge(Li)-Nal(T) coincidence spectrometer. A total of 38γ-rays was observed and the directional correlation has been measured for the 1248.6 keV→602.6 keV→0, 1325.6 keV→602.6 keV→0, 2293.9 keV→602.6 keV→0 and 2693.8 keV→602.6 keV→0 cascades.The energies, intensities and the multipole mixing ratios of the γ-rays in Te have been deduced. Thepopulated levels of Te were identified up to 2.775 MeV.
