Transverse momentum distributions recently measured in the radioactive projectile fragmentation at 790 MeV/nucleon are compared to the extended Serber model calculations. It is shown that the observed widths are roughly consistent with the quasifree stripping of a few loosely bound neutrons from the neutron-rich nuclei.
