Study of deuteron-induced reactions associated with accelerator-driven neutron sources

本文对100MeV以下的氘在Li上引起的反应进行了理论模型分析，这是加速器驱动中子源的候选反应之一。本文用连续离散耦合道理论分析了氘在Li上的弹性破裂过程，用Glauber模型分析了核子剥离过程，用移动源模型分析了预平衡和蒸发过程。计算很好地再现了在前向角实验核子发射谱中观察到的一个突出的凸起。本文的分析表明，在氘在Li上的碎裂反应中，剥离过程比弹性碎裂过程更占主导地位。

A theoretical model analysis was performed for deuteron-induced reactions on Li up to 100MeV, which is one of the candidate reactions used as an accelerator-driven neutron source. The inclusive nucleon spectra from deuteron breakup reactions on Li are analyzed by using the continuum discretized coupled channels theory for elastic breakup process, the Glauber model for nucleon stripping process, and the moving source model for preequilibrium and evaporation processes. The calculation reproduces a prominent bump observed in experimental nucleon emission spectra at forward angles quite well. The present analysis clarifies that the stripping process is more dominant than the elastic breakup process in deuteron breakup reactions on Li.
