摘要
少体系统在高动量转移下的 exclusive 反应为我们提供了研究冷核物质中强子产生与传播的独特途径。在相空间中定义良好的部分，反应振幅呈现对数奇点。这有坚实基础，因其仅依赖于在壳元振幅和核波函数的低动量分量。这是研究强子奇异构型（例如色透明起始）的最佳窗口。它可能在介子光生反应中，更特别地是在奇异 sector，比更经典的电子准弹性散射更早出现。更一般地，那些反应为我们提供了确定各类强子（奇异粒子、矢量介子）与核子散射截面及获取可能奇异态产生的最佳工具。

15 pages; 11 figures During the review process of the paper, the following changes have been implemented: 1- The title has been changed, 2- The abstact and the first paragraph of the introduction have been rephrased for consistency; 3- Figure 10 has been added; 4- The Appedix has been considerably expanded: it gives the full expressions of the elementary photoproduction amplitudes in terms of Pauli spinors and matrices
