We have measured negative secondary-ion yields from phenylalanine, CsI, and Au bombarded by complex ions of 5"28 keV. The primary ions were organic monomer and dimer ions and clusters of CsI. Large enhancements occur in the measured secondary-ion yields for more complex projectiles. We show that secondary-ion yields of Au- atomic species are related to the square of the projectile momentum. 1989 The American Physical Society.
