Abstract

The fracs parameterizations, labeled as fracs-c, have been improved in order to predict the presence of isotopes near the proton drip line produced in projectile fragmentation reactions. By investigating the cross sections for proton-rich isotopes in a series of reactions with energies ranging from intermediate to relativistic, it is shown that the fracs-c parameterizations can predict isotopes near the proton drip line considerably well. The fracs-c parameterizations are suggested to serve as an effective tool for predicting the presence of proton-rich isotopes with large asymmetry in a projectile fragmentation reaction. Different reactions have been investigated to check these results.
