Phys. Rev. Lett. 74, 3569–3572 (1995)One-Neutron Halo of 19CReceived 27 December 1994; published in the issue dated 1 May 1995 We have measured the longitudinal momentum distribution of 18C, 17C, and 16C after the one-neutron breakup of 19C, 18C, and 17C, respectively, using the A1200 fragment separator as an energy-loss spectrometer. The observed narrow width of 44.3±5.9 MeV/c for the 18C fragments indicates that 19C is a new example of a one-neutron halo, so far the heaviest ever observed. The consequences of the obtained results on the structure of the three isotopes 19,18,17C are discussed together with shell-model calculations. © 1995 The American Physical Society URL:
