• 中文摘要： 我們以量度砷71衰變所放出的伽瑪射線來研究鍺71的能階結構。砷71同位素是以能量為 2.38 MeV 的質子束所誘發的反應產生的。所使用的靶為厚靶，成份為濃縮的鍺 70(98.84%) 之二氧化物。本實驗使用高鑑別率的鍺偵測器量度伽瑪射線能譜及其符合能譜。從這些數據，我們提出一個鍺71較低激發態的能階構造圖，其中比以前所發表對砷71衰變研究的結果多了幾個能階，其能量分別為 1261, 1277, 1370, 1415, 1712及1785 KeV.
• 英文摘要： The level structure of is studied by measuring the γ-rays in the decay of . The radioactiveisotope is produced in the reaction with the incident proton energy at 2.38 MeV. Athick target of enriched (98.84%) dioxide is used. The experiment is performed by using high resolu-tion detectors to measure γ-ray single spectrum and coincidence spectra. From these data a level schemefor the low-lying states of is presented. Several levels of energies 1261, 1277, 1370, 1415, 1712, and1785 keV are proposed in addition to those obtained in the previous decay studies.
