Using the Weizsacher-Williams method of virtual quanta, total cross section estimates for the photoproduction of neutral subthreshold pions in carbon-carbon collisions at incident energies below 300 MeV/nucleon are made. Comparisons with recent experimental data indicate that the photoproduction mechanism makes an insignificant contribution to these measured cross sections.
使用魏茨泽克 - 威廉姆斯虚量子方法，对入射能量低于300兆电子伏特/核子的碳 - 碳碰撞中中性亚阈值π介子的光生总截面进行了估算。与最近的实验数据比较表明，光生机制对这些测量的截面贡献不大。
