Multiple-models predictions for drip line nuclides in projectile fragmentation of 40;48Ca, 58;64Ni, and 78;86Kr at 140 MeV/u

Modern rare isotope beam (RIB) factories will significantly enhance the production of extremely rare isotopes (ERI) at or near drip lines. As one of the most important methods employed in RIB factories, the production of ERIs in projectile fragmentation reactions should be theoretically improved to provide better guidance for experimental research. The cross-sections of ERIsproduced in 140 MeV/u 78,86Kr/58,64Ni/40,48Ca + 9Be projectile fragmentation reactions were predicted using the newly proposed models [i.e., Bayesian neural network (BNN), BNN + FRACS, and FRACS, see Chin. Phys. C,46: 074104 (2022)] and the frequently used EPAX3 model.
