The creation of a clustered and neutron-rich midvelocity (“neck” or “hot spot”) region in intermediate-energy heavy-ion collisions is discussed. Reaction simulations suggest that the preponderance of the neutron-rich species in isotopic and isobaric ratios results primarily from the amplification of the initial neutron excess due to d (and by inference α-particle) cluster formation.
