Extrapolation of neutron-rich isotope cross-sections from projectile fragmentation

TL;DR

This paper presents a systematic method to extrapolate neutron-rich isotope cross-sections from projectile fragmentation data, aiding experimental planning and applicable across various radioactive ion beam systems.

Contribution

The study introduces a novel extrapolation technique based on average binding energy trends for predicting unmeasured neutron-rich isotope cross-sections.

Findings

Cross-sections of unmeasured neutron-rich nuclei can be accurately extrapolated.

The method is validated using data from 48Ca and 64Ni beams.

Applicable to other fragmentation systems and facilities.

Abstract

Using the measured fragmentation cross sections produced from the 48Ca and 64Ni beams at 140 MeV per nucleon on 9Be and 181Ta targets, we find that the cross sections of unmeasured neutron rich nuclei can be extrapolated using a systematic trend involving the average binding energy. The extrapolated cross-sections will be very useful in planning experiments with neutron rich isotopes produced from projectile fragmentation. The proposed method is general and could be applied to other fragmentation systems including those used in other radioactive ion beam facilities.
