Double-energy-differential cross sections for the Coulomb four-body problem in a quasiclassical framework
2007
Physical Review A. Atomic, Molecular, and Optical Physics
In a quasiclassical framework, we formulate the double energy differential cross sections for the Coulomb four-body problem. We present results for the triple photoionization from the Li ground state at 220.5, 115, 50 and 3.8 eV excess energies. With the energy of one of the electrons kept fixed, the double energy differential cross sections at 220.5 and 115 excess energies are found to be of "U-shape" (unequal energy sharing), with those at 115 eV being in very good agreement with abinitio
