摘要

我们计算了$^{11}$B$(n,\gamma )^{12}$B反应速率，它是核合成网络中的一个重要组成部分，由共振和非共振俘获贡献。对于共振速率，我们使用了窄共振近似法，而对于非共振贡献，我们则使用库仑解离法计算，其中我们使用了有限范围扭曲波玻恩近似理论。然后，我们将计算出的$^{11}$B$(n,\gamma )^{12}$B反应速率与之前报道的速率以及其他关于$^{11}$B的带电粒子反应进行了比较。

Radiative Neutron Capture Rate of $^{11}$B$(n,\gamma )^{12}$B Reaction from the Coulomb Dissociation of $^{12}$B

We calculate the $^{11}$B$(n,\gamma )^{12}$B reaction rate which is an important constituent in nucleosynthesis networks and is contributed by resonant as well as non-resonant capture. For the resonant rate, we use the narrow resonance approximation whereas the non-resonant contribution is calculated with the Coulomb dissociation method for which we use finite-range distorted wave Born approximation theory. We then compare our calculated rate of $^{11}$B$(n,\gamma )^{12}$B reaction with those reported earlier and with other charged particle reactions on $^{11}$B.

期刊介绍： The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
