C+C聚变反应因其复杂的分子共振而闻名于世，它在核结构研究和天体物理学中都扮演着重要的角色。在与天体物理相关的能量下测量FC+C聚变的截面是非常困难的，因为反应产额很低。为了测量这一重要反应中存在的复杂的共振结构，首次发展了一种有效的厚靶方法，并在能量MeV下应用。仅使用单束能量就可以对相对较宽的能量范围内的横截面进行扫描。在MeV下的测量结果与以前的工作结果进行了比较。这种方法对于寻找1 MeV3 MeV能量范围内潜在存在的共振是有用的。
TheC+C fusion reaction is famous because of its complication of molecular resonances, and it plays an important role in both nuclear structural research and astrophysics. It is extremely difficult to measure the cross sections ofC+C fusions at energies of astrophysical relevance because of the very low reaction yields. To measure the complicated resonant structure that exists in this important reaction, an efficient thick target method has been developed and applied for the first time at energiesMeV. A scan of the cross sections over a relatively wide range of energies can be carried out using only a single beam energy. The result of measurement atMeV is compared with results from previous work. This method will be useful for searching for potentially existing resonances ofin the energy range 1 MeV3 MeV.
