摘要：

The cross sections forCa, recently measured in the 345 A MeVZn+Be reaction,were estimated using the FRACS parametrization and an empirical formula,which are in good agreement.The FRACS parametrization and the empirical formula are combined to predict the cross sections for extreme calcium isotopesCa in theZn+Be reactions at the incident energies of,and 345 A MeV.The dependence of emperical formula parameters on the reaction system,as well as the incident energy,are discussed.The results indicate thatCa can be discovered in reactions ofA MeVZn+Be.The predicted binding energy for extreme neutron-rich isotopes by the spherical relativistic continuum Hartree-Bogoliubov theory was adopted in the calculation.Hence,the planned Beijing Isotope-Separation-On Line Neutron-Rich Beam Facility（BISOL）,which is a third generation radioactive ion beam facility,could provide the opportunity to discoverCa and neighboring neutron-drip line nuclei.
