| Popis: | We present a theory for describing the inner structure of the electron bunch in the bubble regime starting from a random distribution of electrons inside the bubble and subsequently minimizing the system's energy. Consequently, we find a filament-like structure in the direction of propagation that is surrounded by various shells consisting of further electrons. If we specify a 2D initial structure, we observe a hexagonal structure for a high number of particles, corresponding to the close-packing of spheres in two dimensions. The two-dimensional structures are in agreement with the equilibrium slice model (ESM).
