Abstract：
The cross sections for Z=10-19 with isotopes T_z=-3/2 to -5 in the 140A MeV ⁴⁰Ca + ⁹Be projectile fragmentation reaction have been predicted. An empirical formula based on the correlation between the cross section and average binding energy of an isotope has been adopted to predict the cross section. The binding energies in the AME16, WS4, and the theoretical prediction by the spherical relativistic continuum Hartree-Bogoliubov theory have been used. Meanwhile, the FRACS parametrization and the modified statistical abrasion-ablation model are also used to predict the cross sections for the proton-rich isotopes. The predicted cross sections for the T_z=-3 isotopes are close to 10^-10 mb, which hopefully can be studied experimentally. In addition, based on the predicted cross sections, Z=14 is suggested to be a new magic number in the light proton-rich nuclei with T_z ≤ -3/2, for which the phenomenon is much more evident than it is from the average binding energy per nucleon.
