“…Performing a simple test, decreasing the default potential depth in ABRABLA07 [7] from 47. 4 MeV to 40 MeV, we find no significant influence of that parameter on the ability of ABRABLA07 mass number [6,26,[29][30][31][32], and (blue) bold crosses represent data from Ref. [26,31,33,34] for isotopes that have a larger neutron separation energy than proton separation energy.…”

Background: Models describing nuclear fragmentation and fragmentation-fission deliver important input for planning nuclear physics experiments and future radioactive ion beam facilities. These models are usually benchmarked against data from stable beam experiments. In the future, two-step fragmentation reactions with exotic nuclei as stepping stones are a promising tool to reach the most neutron-rich nuclei, creating a need for models to describe also these reactions. Purpose: We want to extend the presently available data on fragmentation reactions towards the light exotic region on the nuclear chart. Furthermore, we want to improve the understanding of projectile fragmentation especially for unstable isotopes.Method: We have measured projectile fragments from 10,12-18 C and 10-15 B isotopes colliding with a carbon target. These measurements were all performed within one experiment, which gives rise to a very consistent dataset. We compare our data to model calculations.Results: One-proton removal cross sections with different final neutron numbers (1pxn) for relativistic 10,12-18 C and 10-15 B isotopes impinging on a carbon target. Comparing model calculations to the data, we find that EPAX is not able to describe the data satisfactorily. Using ABRABLA07 on the other hand, we find that the average excitation energy per abraded nucleon needs to be decreased from 27 MeV to 8.1 MeV. With that decrease ABRABLA07 describes the data surprisingly well.Conclusions: Extending the available data towards light unstable nuclei with a consistent set of new data have allowed for a systematic investigation of the role of the excitation energy induced in projectile fragmentation. Most striking is the apparent mass dependence of the average excitation energy per abraded nucleon. Nevertheless, this parameter, which has been related to final-state interactions, requires further study.

“…To do that we use data from Refs. [6,26,[29][30][31][32][33][34], as summarized in Table II, and perform ABRABLA07 calculations with f EE between 0.5 and 4 in intervals of 0.1. With the requirements of beam energies above 100 AMeV and data available in tabulated form, we used all to our knowledge published 1pxn removal data available.…”

On the basis of systematic measurements of fragmentation reactions, which provide a detailed overview on the velocity distributions of residual nuclei, an improved description of the kinematical properties of the fragmentation residues is established. This work is dedicated to the fluctuations of their momentum distributions. In contrast to previous investigations, limited to close-to-projectile fragments, we extended our study to the entire production range, down to the lightest observed fragments. In this context, beside the contribution of abrasion and evaporation processes, we considered the effect of the thermal break-up on the width of the momentum distributions. Using approximated theoretical descriptions of the different reaction stages, a new analytical formula for the variance of the momentum distribution is derived, which is well adapted to technical applications.
