我们分析了从阈值以上几个千兆电子伏开始的中等光子能量范围内的氘核光生矢量介子的横截面。我们重现的步骤，在推导传统的非相对论性的Glauber表达式的基础上，一个有效的图解方法，同时进行修正费米运动和中能运动学效应。我们表明，对于中能矢量介子生产，通常的Glauber分解打破，我们推导出通常的Glauber方法的纵向核子动量的线性顺序的修正。我们的分析的目的是建立方法，探索有趣的物理在生产机制的{phi}介子和重矢量介子。我们演示了如何忽略Glauber分解的故障可能会导致从核数据中提取的基本横截面的测量误差。
We analyze the cross section for vector meson photoproduction off a deuteron for the intermediate range of photon energies starting at a few giga-electron-volts above the threshold and higher. We reproduce the steps in the derivation of the conventional nonrelativistic Glauber expression based on an effective diagrammatic method while making corrections for Fermi motion and intermediate-energy kinematic effects. We show that, for intermediate-energy vector meson production, the usual Glauber factorization breaks down, and we derive corrections to the usual Glauber method to linear order in longitudinal nucleon momentum. The purpose of our analysis is to establish methods for probing interesting physics in the production mechanism for {phi} mesons and heavier vector mesons. We demonstrate how neglecting the breakdown of Glauber factorization can lead to errors in measurements of basic cross sections extracted from nuclear data.
