由极高能宇宙射线引发的大量空气簇射在深度上表现出纵向发展，具有单一的明确定义的簇射最大值。然而，一小部分阵雨的轮廓与这种平均行为有很大的不同。在极端的情况下，这种异常的纵向廓线甚至可以有两个不同的簇射极大值。我们讨论的主要相互作用，导致这样的配置文件的属性。模拟被用来估计依赖于初级能量，质量和强子多粒子生产在非常高的能量的特征的异常配置文件的速率。
The bulk of air showers initiated by very high energy cosmic rays exhibits a longitudinal development in depth with a single well-defined shower maximum. However, a small fraction of showers has a profile that differs considerably from this average behaviour. In extreme cases, such anomalous longitudinal profiles can even have two distinct shower maxima. We discuss the properties of the primary interactions that lead to such profiles. Simulations are used to estimate the rate of anomalous profiles in dependence of primary energy, mass, and characteristic features of hadronic multiparticle production at very high energies.
