介绍利用中子转移反应和镜像核的电荷对称性来间接研究丰质子核的(p,γ)反应。该方法有助于更充分地利用北京HI-13串列加速器次级束流线(GIRAFFE)上现有次级束流,拓宽其实验研究范围,间接得出质子辐射俘获截面(或反应率)且减小其不确定性(相对于已有数据)。在GIRAFFE上利用逆运动学测量了8Li(d,p)9Li反应的角分布,通过该方法间接确定了天体物理重要反应8B(p,γ)9C的直接俘获贡献。作为不同于以往的方法,给8B(p,γ)9C反应的现有研究结果提供了一独立的交叉检验。分析26Mg(d,p)27Mg反应基态、第一、第二激发态的角分布,间接确定26Si(p,γ)27P反应的直接和共振俘获贡献,首次从实验上导出26Si(p,γ)27P反应的直接俘获贡献。此方法也可以用于其它一系列重要的天体物理反应的研究。
The indirect (p, γ) reaction of abundant proton nuclei is described using the charge symmetry of the neutron transfer reaction and the mirror nucleus. This method can help to make full use of existing secondary beams on Beijing HI-13 Tandem Accelerator Secondary Beamline (GIRAFFE) to broaden the range of experimental research and indirectly obtain the proton capture cross section (or reaction rate) And reduce its uncertainty (relative to the existing data). The angular distribution of the 8Li (d, p) 9Li reaction was measured by inverse kinematics on GIRAFFE. The direct capture contribution of the astrophysically important 8B (p, γ) 9C indirectly determined by this method. As an alternative to the previous method, the results of prior studies of 8B (p, gamma) 9C reactions provide an independent cross-test. The direct and resonant capture contributions of the 26Si (p, γ) 27P reaction were indirectly determined by analyzing the angular distribution of the ground state and the first and second excited states of 26Mg (d, p) 27Mg reaction. Direct capture contribution of 27P reaction. This method can also be used for a number of other important astrophysical reactions.
