| 摘 要： | 简单介绍了利用LNS的回旋加速器产生的^116。Sn束轰击^12C和^24Mg靶的实验装置以及实验过程．该实验通过MEDEA探测器测量了由全熔合与非全熔合反应产生的较低激发能区(160-300MeV)质量数A≈125的热核的巨偶极共振特性，比较了不同靶子、不同束流能量时巨偶极共振的7产额的变化．The experiment was carried out at the National Laboratory of South in Italy using~(116)Sn beam of 17 and 23 MeV/u delivered from the Superconducting Cyclotron impinging on~(12)C and~(24)Mg targets. The hot nuclei have been formed by complete and incomplete fusion reactions. The characteristics of the giant dipole resonance(GDR) in hot nuclei of mass A≈125 at lower excitation energies between 160 and 300 MeV have been measured with the multi element detector array (MEDEA) detector. A comparison of GDR ...
