40-，90-，和150-MeV的质子引起的反应上的/sup 238/U目标的一致裂变碎片之间的角相关已被测量。从这些数据中，线性动量转移分布已被推导出来，然后与质子和更复杂的射弹的其他结果进行比较。在每个核子的基础上，质子表现出最大的平均线性动量转移值的任何弹丸的能量范围从E/A = 40至1000兆电子伏。这可以理解的基本散射截面，并定性地证明了核内级联计算。级联和预复合衰变计算再现线性动量转移分布与中等成功。
Angular correlations between coincident fission fragments have been measured for 40-, 90-, and 150-MeV proton-induced reactions on a /sup 238/U target. From these data linear momentum transfer distributions have been derived, which are then compared with other results for protons and more complex projectiles. On a per nucleon basis, protons exhibit the largest average linear momentum transfer values of any projectile over the energy range from E/A = 40 to 1000 MeV. This can be understood in terms of fundamental scattering cross sections, and is qualitatively demonstrated by intranuclear cascade calculations. Both cascade and precompound decay calculations reproduce the linear momentum transfer distributions with moderate success.
