Abstract :
The longitudinal momentum distributions of 34 neutron-rich isotopes of elements produced by fragmentation of a 76Ge beam at 132 MeV/u with 13 ≤ Z ≤ 27 were scanned using a novel experimental approach where a variety of targets with different thicknesses was used with the fragment separator at constant magnetic rigidity. In comparison to models that describe the shape and centroid of fragment momentum distributions, a parametrization based on the measured data was derived. Details of the transmission calculations, the analysis of their uncertainties, as well as the general analysis of momentum distributions and deduced cross-sections obtained with this approach are presented.
