~(25)Mg(p,γ)~(26)Al反应是恒星爆发性氢燃烧镁铝循环中的关键反应,精确测量其在恒星能量的反应截面是解决~(26)Al、~(26)Mg等核素超丰疑难问题的关键。由于该反应的58 keV共振难以直接测量,目前国际上只有3家实验室分别在不同能量下利用~(25)Mg(~3He,d)~(26)Al_(6.364)~*反应进行了间接测量,但均受~(16)O(~3He,d)~(17)F_(0.495)~*反应的干扰,测得角分布的误差较大,这也导致了最终的共振参数存在将近两倍的分歧,因此很有
The reaction of ~ (25) Mg (p, γ) ~ (26) Al is a key reaction in the stellar explosive hydrogen combustion of magnesium and aluminum. The accurate measurement of its reaction cross section at stellar energy is the solution of ) Mg and other nuclides ultra-tough difficult problem. Because of the difficulty of direct measurement of the 58 keV resonance of the reaction, only three laboratories in the world have been indirectly exposed to ~ (25) Mg (~ 3He, d) ~ (26) Al_ (6.364) ~ * reactions at different energies However, the error of the angular distribution was larger when the interference of ~ (16) O (~ 3He, d) ~ (17) F_ (0.495) ~ * was measured. This also led to the fact that the final resonance parameters were nearly two Times differences, so very much
