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.

一种用于高电荷和能量离子传输的格林函数方法

开发了使用格林函数方法的重离子传输代码。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，而高阶碰撞项则使用非微扰方法进行评估。最近修订的 NUCFRG 数据库用于评估该解决方案，以便与 625A MeV 20Ne 和 517A MeV 40Ar 离子束的实验数据进行比较。发现了与氖离子衰减特性的改进一致性，并且为氩离子在水中的传输获得了合理的一致性。
