摘要:

在过去的几十年里,逆运动学下散裂、碎裂和库仑激发诱导裂变反应的测量为精确研究裂变动力学和大形变下的核结构提供了宝贵的数据,这些数据涵盖了多种稳定和非稳定重核。为了更进一步,我们提出利用逆运动学中的准自由(p,2p)散射反应来诱导裂变,该方法通过两个出射质子的四动量重建复合裂变系统的激发能。因此,这一新方法可能将激发能与裂变碎片的电荷和质量分布以及裂变概率相关联,从而首次直接同时测量裂变产额对温度的依赖性和奇异重核的裂变垒高度。基于该方法的首个实验最近已在GSI/FAIR设施完成,本文详细描述了实验装置。

英文摘要:

In the last decades, measurements of spallation, fragmentation and Coulex induced fission reactions in inverse kinematics have provided valuable data to accurately investigate the fission dynamics and nuclear structure at large deformations of a large variety of stable and non-stable heavy nuclei. To go a step further, we propose now to induce fission by the use of quasi-free (p,2p) scattering reactions in inverse kinematics, which allows us to reconstruct the excitation energy of the compound fissioning system by using the four-momenta of the two outgoing protons. Therefore, this new approach might permit to correlate the excitation energy with the charge and mass distributions of the fission fragments and with the fission probabilities, given for the first time direct access to the simultaneous measurement of the fission yield dependence on temperature and fission barrier heights of exotic heavy nuclei, respectively. The first experiment based on this methodology was realized recently at the GSI/FAIR facility and a detailed description of the experimental setup is given here.
