Quantum collision theory for astrophysics, fusion energy and hadron therapy

该项目旨在研究带电粒子与复杂原子和分子相互作用的碰撞过程。虽然电子、正电子和离子与简单原子和分子的碰撞理论在最近几年得到了发展，但由于靶的可计数和不可计数的无限光谱、长程库仑势以及靶的多中心性质和重排过程的混合，相应的计算模型是困难的。这些困难可以使用收敛的紧耦合方法来克服。该项目计划将该方法应用于当前感兴趣的各种应用中的复杂量子碰撞系统，如聚变能源、照明、天体物理学以及癌症成像和治疗。

The project intends to investigate collision processes involving charged particles interacting with complex atoms and molecules. Although the theory of electron, positron and ion collisions with simple atoms and molecules has advanced in recent years, the corresponding computational modelling is difficult due to the mix of the countably and uncountably infinite spectrum of the target, the long-range Coulomb potential, and the multicentre nature of the target and the rearrangement processes. These difficulties could be overcome using a convergent close-coupling method. This project plans to apply the method to complex quantum collision systems in diverse applications of current interest such as fusion energy, lighting, astrophysics, and cancer imaging and therapy.
