论文摘要
背景:核转移反应是研究核结构的有用工具。对于涉及每周结合核的反应,分解效应可以起着重要作用,并且在这种情况下,理论计算可能是计算昂贵的。 目的:利用Lagrange-Mesh和R-Matrix方法进行核转移反应。 方法:我们使用绝热扭曲的波浪近似(ADWA)方法,该方法可以更简单地处理分解效应。在我们的方法中,我们应用R-Matrix方法将其与Lagrange-Mesh方法相结合,该方法已知可以提供快速准确的计算。 结果:作为测试案例,我们计算了54FE(D,P)55FE反应的横截面的角度分布,其中Deuteron Breakup效应起着重要作用。 结论:我们表明这些方法在ADWA框架中很好地工作,我们期待将这些方法应用于耦合的通道计算中。
Background: Nuclear transfer reactions are a useful tool to study the structure of a nucleus. For reactions involving weekly bound nuclei, breakup effects can play significant role and theoretical calculations can be computational expensive in such cases. Purpose: To utilize the Lagrange-mesh and R-matrix methods for nuclear transfer reactions. Methods: We use the adiabatic distorted wave approximation (ADWA) method which can approximately treats the breakup effects in a simpler manner. In our approach, we apply the R-matrix method combining it with the Lagrange-mesh method, which is known to provide the fast and accurate computations. Results: As a test case, we calculate the angular distribution of the cross sections for the 54Fe(d, p)55Fe reaction, where deuteron breakup effects play important role. Conclusions: We show that these methods work well in the ADWA framework, and we look forward to applying these methods in coupled channel calculations.
