Abstract: We study the double electronic emission by photon impact from He in thecenter of a spherical fullerene, which is modeled by a square-well shell. Thissystem exhibits a manifold of avoided crossings as a function of the welldepth, and present mirror colapses. However, this symmetry is broken in thetriple differential cross section due to the delocalization of the He electronsin the initial state. Moreover, the fullerene potential involves higher angularmomenta partial waves to be included in the process, which modifies thewell-known two-lobe cross section from isolated He.
