| Popis: | 6 pages, 5 figures.-- PACS nrs.: 25.60.Gc; 25.70.Mn; 27.20.+n.-- ArXiv pre-print available at: http://arxiv.org/abs/nucl-ex/9810011 The fragment separator FRS at GSI was used as an energy-loss spectrometer to measure the longitudinal momentum distributions of C-16,C-18 fragments after one-neutron removal reactions in C-17,C-19 impinging on a carbon target at about 910 MeV/u. The distributions in the projectile frames are characterized by a FWHM of 141 ± 6 MeV/c for C-16 and 69 ± 3 MeV/c for C-18. The results are compared with experimental data obtained at lower energies and discussed within existing theoretical models.
