Abstract

Correlations between intermediate-mass fragments (IMF's) and heavy fragments were measured for ${}^{18}O$ -induced reactions on ${}^{nat}{Ag}$ and ${}^{197}{Au}$ at $\frac{E}{A} = 84$ MeV. Correlations of two coincident IMF's show a depletion at small relative velocities $v_{rel} \leq 1$ cm/ns, reflecting the proximity of the two IMF's at the point of creation. However, the time scales for IMF emission derived from this correlation are similar to those of binary-IMF-heavy-recoil coincidences which indicates a sequential nature of multifragment emission in these reactions.
