Production cross-sections of light neutron-rich nuclei from 40Ar fragmentation at about 1 GeV/nucleon

Using a primary beam of Ar-40 at similar to 1A GeV impinging on a Be target, the production cross-sections of light neutron-rich fragments from projectile fragmentation were measured at the projectile-fragment separator FRS at GSI. The experimental cross-sections were obtained for isotopes of the elements B to F both close to stability and near the neutron drip line. These data are compared to the results of the empirical parametrization EPAX. We also compare the results to those measured previously at LBL, As an additional result, the particle instability of O-26 has been confirmed. (C) 2000 Elsevier Science B.V. All rights reserved.
