Phys. Rev. Lett. 86, 1986–1989 (2001)Reaction Mechanisms for Two-Neutron Halo BreakupReceived 22 September 2000; published in the issue dated 5 March 2001 We describe a reaction mechanism which is consistent with all available experimental information of high energy three-body breakup processes. The dominating channels are removal of one of the three halo particles leaving the other two either undisturbed or absorbed. We compare with the commonly used deceptive assumption of a decay through two-body resonance states. Our predictions can be tested by measuring neutron-neutron invariant mass spectra. © 2001 The American Physical Society URL:
