测量了0.8 GeV和1.5 GeV质子入射时，铁和铅的最正向中子产生双微分截面。用飞行时间法(TOF)测量了中子。作为中子探测器，NE213液体有机闪烁体设置在0°。中子探测效率由蒙特卡罗模拟程序SCINFUL-QMD计算得到。将本实验数据与其他文献报道的实验数据以及基于核内级联蒸发(INC/E)和量子分子动力学(QMD)模型的计算程序的结果进行了比较。对于与Δ形成有关的中子，目前的数据偏离了这些代码的预测，并在0.8GeV和1.5GeV的入射中给出了它们之间的量级。
Neutron-production double-differential cross sections of iron and lead for 0.8 and 1.5 GeV protons incidences were measured in the most-forward direction. Neutrons were measured by the time-of-flight (TOF) method. An NE213 liquid organic scintillator was set at 0° as a neutron detector. Neutron detection efficiencies were obtained by calculations with a Monte Carlo simulation code SCINFUL-QMD. The present experimental data were compared with other reported experimental data and the results of calculation codes based on Intranuclear-Cascade-Evaporation (INC/E) and Quantum Molecular Dynamics (QMD) models. For neutrons associated with Δ formation, the present data deviated from predictions of these codes, and gave magnitudes between them in both 0.8 and 1.5 GeV incidences.
