A. Menchacarocha et al., ARE THE TOROIDAL SHAPES OF HEAVY-ION REACTIONS SEEN IN MACROSCOPIC DROP COLLISIONS, Revista Mexicana de Fisica, 42, 1996, pp. 198-202
Experiments involving the collisions of water, and mineral oil, drops
are reported. The aim is to search for toroidal configurations predict
ed by, both, macroscopic fluid dynamic and nuclear models. Instead, we
find the formation of thin liquid sheets surrounded by a somewhat thi
cker rim presenting a fingering instability.
