| dc.description | Radioactive beams of Borromean halo-like nuclei like <sup>11</sup>Li have provided possibilities for studying the exotic structure of such objects. Since the information is obtained in collision studies, in particular from break-up channels, one has to disentangle the structure information from the reaction mechanism. A satisfactory treatment within a three-body model for the projectile requires a four-body continuum calculation. As an exploratory step towards this end, we give a phenomenological discussion based on data for <sup>6</sup>He and <sup>11</sup>Li projectiles for high and low energies from 1 GeV A<sup>-1</sup> down to 30 MeV A<sup>-1</sup>. Data for both transverse and longitudinal momentum distributions for the three-body constituents of these projectiles are used. We argue that the data can be consistently understood in a picture where the high-energy data mainly correspond to direct break-up of the projectile ground state in a Serber model, while the low-energy data exhibit the fingerprint of a sequential break-up process via a narrow low-lying resonance, observed in <sup>6</sup>He but hitherto not identified in <sup>11</sup>Li. |
