论文摘要

使用Hussein和McVoy [1]开发的包容性非弹性分裂(INEB)的理论报告了计算放射性核上中子捕获横截面的替代方法。参考文献中提出的统计耦合通道理论。 [2]在随机矩阵的领域进一步扩展。还分析了与弹丸的反应和目标是两簇核的情况,并应用于迪特隆靶标的散射[3]。还讨论了将理论扩展到三个群集目标上的三个群集弹丸事件。这里描述的理论发展应开放新的可能性,以使用间接方法获得有关放射性核的中子截面的信息。

Alternative methods to calculate neutron capture cross sections on radioactive nuclei are reported using the theory of Inclusive Non-Elastic Breakup (INEB) developed by Hussein and McVoy [1]. The statistical coupled-channels theory proposed in Ref. [2] is further extended in the realm of random matrices. The case of reactions with the projectile and the target being two-cluster nuclei is also analyzed and applications are made for scattering from a deuteron target [3]. An extension of the theory to a three-cluster projectile incident on a two-cluster target is also discussed. The theoretical developments described here should open new possibilities to obtain information on the neutron capture cross sections of radioactive nuclei using indirect methods.
