Abstract

The combined use of the inverse kinematics technique and the advanced detection setup R³B (Reactions with Relativistic Radioactive Beams) at GSI/FAIR provides unique opportunities to study the fission process. This approach provides access to the complete isotopic identification of the two fission fragments, the precise determination of their velocities and the measurement of the neutrons and gammas emitted in coincidence, for a wide range of unstable fissile nuclei. In addition, quasi-free NN scattering represents a surrogate reaction to induce fission, allowing the complete identification of the fissioning system in terms of isotopic composition and excitation energy. The manuscript describes the technical realisation of these experiments as well as the physics programme and some preliminary results.

准自由神经网络散射反应在逆运动学中的裂变研究

GSI/FAIR的逆运动学技术和先进的R3B（相对论放射性光束反应）探测装置的结合使用为研究裂变过程提供了独特的机会。这种方法提供了对两个裂变碎片的完整同位素鉴定，精确确定它们的速度和测量巧合发射的中子和伽马，用于广泛的不稳定裂变核。此外，准自由神经网络散射代表了诱导裂变的替代反应，从而可以从同位素组成和激发能方面完整地识别裂变系统。手稿描述了这些实验的技术实现以及物理程序和一些初步结果。
