Using a one-dimensional transport theory for laboratory heavy ion propagation, evaluations of typical energy-independent transport coefficient approximations are made by comparing theoretical depth-dose predictions to published experimental values for incident 670 MeV/nucleon 20Ne beams in water. Results are presented for cases where the input nuclear absorption cross sections, or input fragmentation parameters, or both, are fixed.
利用一维输运理论来研究实验室中重离子的传播,通过将理论深度剂量预测值与已发表的关于能量为670 MeV/核子的20Ne束在水中的实验值进行比较,对典型的与能量无关的输运系数近似值进行了评估。给出了输入核吸收截面、或输入碎裂参数、或两者均固定的情况下的结果。
