A heavy-ion transport code using Green's function methods is developed. The low-order perturbation terms exhibiting the greatest energy variation are used as dominant energy-dependent terms, and the higher order collision terms are evaluated using nonperturbative methods. The recently revised NUCFRG database is used to evaluate the solution for comparison with experimental data for 625A MeV 20Ne and 517A MeV 40Ar ion beams. Improved agreements with the attenuation characteristics for neon ions are found, and reasonable agreement is obtained for the transport of argon ions in water.
开发了一种使用格林函数方法的重离子输运代码。将表现出最大能量变化的低阶微扰项用作主要的能量相关项,并使用非微扰方法评估高阶碰撞项。使用最近修订的NUCFRG数据库来评估该解,以便与625A MeV 20Ne和517A MeV 40Ar离子束的实验数据进行比较。发现与氖离子的衰减特性有更好的一致性,并且对于氩离子在水中的输运也获得了合理的一致性。
