Abstract

The particle stability of B19 and the particle instability of B18 are demonstrated. Light neutron-rich nuclei were searched for among the projectile fragments resulting from interactions of a 670A- MeV Fe56 beam in a 7.9-g/cm2 Be target. A detector consisting of a magnetic spectrometer, threshold Cherenkov paddles, and scintillator paddles was used to determine the charge and mass of the projectile fragments.
