Lg. Sobotka et al., CLUSTERED AND NEUTRON-RICH LOW-DENSITY NECK REGION PRODUCED IN HEAVY-ION COLLISIONS, Physical review. C. Nuclear physics, 55(4), 1997, pp. 2109-2111
The creation of a clustered and neutron-rich midvelocity (''neck'' or
''hot spot'') region in intermediate energy heavy-ion collisions is di
scussed. Reaction simulations suggest that the preponderance of the ne
utron-rich species in isotopic and isobaric ratios results primarily f
rom the amplification of the initial neutron excess due to d (and by i
nference alpha-particle) cluster formation.
