通过将理论扭曲波玻恩近似计算与现有的实验数据拟合，系统地提取了入射氘能量达100 MeV的~（12）C、~（27）Al、~（40）Ca和~（58）Ni（d，p）反应的光谱因子.提取的光谱因子显示出相似的入射能量依赖性的所有目标核。推导了描述能量依赖关系的经验表达式，并在专门为氘诱导反应开发的计算程序系统中实现。用该程序系统计算了~（27）Al（d，p）~（28）Al在阈能到20 MeV的反应截面，并较好地再现了~（12）C和~（58）Ni在56和100 MeV的（d，xp）反应的双微分截面。
Spectroscopic factors for the (d,p) reactions on 12C, 27Al, 40Ca, and 58Ni for incident deuteron energies up to 100 MeV were extracted systematically by fitting theoretical distorted wave Born approximation calculations to the existing experimental data. The extracted spectroscopic factors show similar incident energy dependence for all the target nuclei. An empirical expression describing the energy dependence has been deduced and implemented in a computational code system developed specially for deuteron-induced reactions. The calculation with the code system reproduces the measured 27Al(d,p)28Al cross sections in the incident energy range from the threshold to 20 MeV and the measured double-differential cross sections for (d,xp) reactions on 12C and 58Ni at 56 and 100 MeV fairly well.
