Phys. Rev. A 61, 062711 (2000) [7 pages]Chaotic scattering in collinear Ze-e- three-body Coulomb systemsReceived 11 October 1999; published 17 May 2000 We study the collinear chaotic scattering between an electron and a one-electron ion (e.g., He+) with negative total energy. The global dynamics of the unbounded motion in phase space can be illustrated by introducing two submanifolds of critical injecting and critical escaping. We find a type of bifurcation of chaotic scattering resulted from the tangency between these two submanifolds, which explains the emergence or disappearance of an extra zeroth-order chaotic band in the scattering functions as the nuclear charge Z is changed. © 2000 The American Physical Society URL:
