SATURNE 加速器测量了 0.8、1.2 和 1.6 GeV 的 Pb 靶上质子诱发反应中散裂中子的产生。在较宽的角度范围内获得双微分截面，从中可以推断出能量高于 2 MeV 时每个反应的平均中子多重数。将结果与使用包括两种不同核内级联 (INC) 模型的高能量传输代码执行的计算进行比较：结果表明，Cugnon INC 模型比 Bertini 模型与数据具有更好的一致性，这主要是因为改进了核子-核子横截面和泡利阻断处理。 © 1999 美国物理学会。
Spallation neutron production in proton induced reactions on Pb targets at 0.8, 1.2, and 1.6 GeV has been measured at the SATURNE accelerator. Double-differential cross sections were obtained over a broad angular range from which averaged neutron multiplicities per reaction were inferred for energies above 2 MeV. The results are compared with calculations performed with a high energy transport code including two different intranuclear cascade (INC) models: it is shown that the Cugnon INC model gives a better agreement with the data than the Bertini one, mainly because of improved nucleon-nucleon cross sections and Pauli blocking treatment. © 1999 The American Physical Society.
