Emission of intermediate mass fragments in the heavy ion interaction of (14.0 MeV/u) Pb plus Au

We have studied the heavy ion interactions of (14.0 MeV/u) Pb + Au using tw o threshold detectors, mica and CN-85. A thin layer of Au was deposited on each of the three mica and two CN-85 detector pieces. These target-detector assemblies were exposed to a beam of 14.0 MeV/u ph ions having the fluence of 1.5 x 10(6) cm(2) at CSI, Darmstadt, Germany. After removing the target material and etching the samples in appropriate etchants, we scanned 32.29 cm(2) and 24.97 cm(2) area of mica and CN-85, respectively. Based on the o bserved number of events of various multiplicities, we have determined the total as well as partial experimental reaction cross-sections. Tt is shown that a significant number of intermediate mass fragments are emitted alongw ith the heavy fragments in the present reaction. (C) 2001 Elsevier Science B.V. All rights reserved.
