A. Menchacarocha et al., ROTATING-LIQUID-DROP MODEL LIMIT TESTED ON MACROSCOPIC DROPS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 47(2), 1993, pp. 1433-1436
The collisions of m = 0.3-2.0 g, v = 5-50 cm/s mercury drops are studi
ed experimentally. A transition between a fusion and a nonfusion outco
me is observed, and found to be influenced by angular momentum. The ma
ss dependence measured for the limiting angular momentum L(c)(expt) is
compared with predictions L(c)(theor) of a surface-potential model wi
dely used in nuclear physics. A systematic L(c)(expt) less-than-or-equ
al-to L(c)(theor) discrepancy is found in these and in other drop coll
ision data. Dynamical considerations and the use of more elaborate sur
face shapes than those assumed by the model are found to reduce the di
sagreement.
