索菲亚（Study On Fission with Aladin）是在GSI进行的一项关于核裂变的创新实验计划。2012年8月，我们使用FRS提供的缺中子锕系元素和前锕系元素的相对论次级束，并在逆运动学中研究了它们由电磁相互作用引起的裂变。这项实验将首次提供完整的同位素产量（核电荷和质量）的两个碎片在广泛的裂变核从238 Np下降到183 Hg。在这篇文章中，我们讨论了实验装置和目前有前途的初步结果。
SOFIA (Study On FIssion with Aladin) is an innovative experimental programme on nuclear fission carried out at GSI. In August 2012, we used relativistic secondary beams of neutron-deficient actinides and pre-actinides provided by the FRS and studied their fission, induced by electromagnetic interaction, in inverse kinematics. This experiment will provide for the first time complete isotopic yields (nuclear charge and mass) for both fragments over a broad range of fissioning nuclei from238Np down to 183Hg. In this article, we discuss the experimental set-up and present promising preliminary results.
