Projectile fragmentations of 11Li, 8He, and 6He have been measured at 0.79 GeV/nucleon. Production cross sections and momentum distributions of the produced isotopes (Z≥2) are measured inclusively. Transverse-momentum distributions of 9Li from the fragmentation of 11Li show two Gaussian components of different widths. The width of the wide component is consistent with the values observed in the fragmentation of stable nuclei, whereas the other component shows an extremely narrow width reflecting the weak binding of the two outer neutrons in the 11Li nucleus.
