J. Toke et al., DYNAMICAL PRODUCTION OF INTERMEDIATE-MASS FRAGMENTS IN PERIPHERAL BI-209-136 COLLISIONS AT E(LAB)(XE)A=28 MEV/, Nuclear physics. A, 583, 1995, pp. 519-524
Intermediate-mass fragments (IMF) from the reaction Bi-209+Xe-136 at E
(lab)/A=28 MeV have been measured in coincidence with other charged re
action products, as well as with neutrons. The IMF emission patterns a
re seen to exhibit signatures of two mechanisms - statistical emission
from the fully accelerated massive reaction partners and a fast dynam
ical emission from a single effective source. The latter mechanism, po
ssibly involving a multiple neck rupture, becomes dominating for least
dissipative collisions characterized by low associated light particle
multiplicities.
