寻找生产富质子和富中子同位素的有效途径是实验和理论核反应研究以及放射性废物核嬗变实际应用的主要驱动力之一。为了有效地产生核，需要反应机制和能量的最佳组合。本文报道了由一个质子和一个中子组成的结合能很弱的、容易破碎的氘引起的不完全聚变的研究。本反应研究是通过逆运动学方法直接测量50 MeV/u107 Pd的质子和氘反应截面来实现的。结果提供了直接的实验证据，在高能量下的截面增强的开始，表明不完全融合的潜力，由松散结合的核产生富含质子的同位素和核嬗变的放射性废物。
Searching for effective pathways for the production of proton-rich and neutron-rich isotopes is one of the main driving forces behind experimental and theoretical nuclear reaction studies as well as for practical applications in nuclear transmutation of radioactive waste. To produce nuclei effectively, an optimal combination of reaction mechanism and energy is required. We report a study on incomplete fusion induced by deuteron, which contains one proton and one neutron with a weak binding energy and is easily broken up. This reaction study was achieved by measuring directly the cross sections for both proton and deuteron for107Pd at 50 MeV/uvia inverse kinematics technique. The results provide direct experimental evidence for the onset of a cross-section enhancement at high energy, indicating the potential for incomplete fusion induced by loosely-bound nuclei for creating proton-rich isotopes and nuclear transmutation of radioactive waste.
