Abstract—
The charge exchange reaction (3He, t) is studied using target odd nuclei of 45Sc and 197Au at 29‑MeV 3He beam energy. The angular distributions of the emission of deuterons and tritium in the 45Sc(3He, t)45Ti and 197Au(3He, t)197Hg reactions are studied. Experiments have shown that the maximum values of the cross sections for tritium emission reactions are achieved at angles close to the grazing angle. This indicates that the charge exchange reactions are of peripheral nature. The angular differential cross sections for the triton emission upon the population of the ground and excited states in 45Ti nuclei are accurately measured for the 45Sc(3He, t) 45Ti reaction.

摘要——
使用45 Sc 和197 Au 的目标奇数核在 29-MeV 3 He 束能量下研究电荷交换反应 ( 3 He, t )。45 Sc( 3 He, t ) 45 Ti 和197 Au( 3 He, t ) 197中氘和氚发射的角分布研究了汞反应。实验表明,氚发射反应的横截面的最大值是在接近掠射角的角度实现的。这表明电荷交换反应具有外围性质。对于45 Sc( 3 He, t ) 45 Ti 反应,精确测量了45 Ti 原子核中基态和激发态布居的氚核发射角微分截面。
