由中国原子能科学研究院串列加速器HI-13提供的束流能量为32MeV的7Li通过重离子熔合蒸发反应70Zn(7Li,3n)74As来布居74As的高自旋态。实验采用质量厚度为0.93mg/cm2金衬的70Zn靶,70Zn的质量厚度为2.15mg/cm2。由12个带有反康普顿装置的HPGe探测器和2个平面HPGe探测器组成的探测阵列,用来探测反应产物退激发时发射的γ射线。共探测到92×106个γ-γ符合事件。
The 7Li with a beam energy of 32 MeV provided by the tandem accelerator HI-13 of the Chinese Academy of Atomic Energy used the heavy ion fusion evaporation reaction 70Zn (7Li, 3n) 74As to occupy the high spin state of 74As. The experiment uses a 70Zn target with a gold thickness of 0.93 mg / cm2 and a mass thickness of 70Zn of 2.15 mg / cm2. A probe array consisting of 12 HPGe detectors with anti-Compton devices and two planar HPGe detectors is used to detect the gamma rays emitted when the reaction product is deactivated. A total of 92 × 106 γ-γ coincidence events were detected.
