Discovery of 60Ca

ORAL

Abstract

The discovery of the important neutron-rich nucleus 60Ca and seven others near the limits of nuclear stability is reported from the fragmentation of a 345 MeV/u 70Zn projectile beam on 9Be targets at the Radioactive Ion-Beam Factory of the RIKEN Nishina Center. The produced fragments were analyzed and unambiguously identified using the BigRIPS two-stage in-flight separator. The results are compared with the drip lines predicted by a variety of mass models.
