MCNP6、MCNPX和MARS15的CEM和LAQGSM事件发生器的概述和验证
Overview and Validation of the CEM and LAQGSM Event Generators for MCNP6, MCNPX, and MARS15
摘要：
简要介绍了我们的CEM和LAQGSM事件发生器的最新版本所使用的核内级联，预平衡，蒸发，裂变，合并和费米破裂模型，重点是我们最新开发的所有这些模型。最近开发的“S”和“G”版本的我们的代码，考虑多重碎裂后形成的预平衡阶段的反应时，他们的激发能是超过2A MeV的统计多重碎裂模型（SMM）的代码由Botanical等人（“S”代表SMM）和类裂变的二元衰变模型GEMINI由慈善（“G”代表GEMINI），分别进行了概述。基准的例子，我们的模型对各种各样的粒子粒子，粒子核，核-核反应的实验数据，涉及到一些最近的测量感兴趣的加速器辐射诱导激活，进行了讨论。
英文摘要：
A brief description of the IntraNuclear cascade, preequilibrium, evaporation, fission, coalescence, and Fermi breakup models used by the last versions of our CEM and LAQGSM event generators is presented, with a focus on our latest development of all these models. The recently developed "S" and "G" versions of our codes, that consider multifragmentation of nuclei formed after the preequilibrium stage of reactions when their excitation energy is above 2A MeV using the Statistical Multifragmentation Model (SMM) code by Botvina et al. ("S" stands for SMM) and the fission-like binary-decay model GEMINI by Charity ("G" stands for GEMINI), respectively, are overviewed as well. Examples of benchmarking our models against a large variety of experimental data on particle-particle, particle nucleus, and nucleus-nucleus reactions, involving some very recent measurements of interest to accelerator radiation induced activation, are discussed.
