Heavy ion interactions of (14.0 MeV/u) Pb with U

The interactions of Pb-208 projectiles with U-nat target have been studied at 14.0 MeV/u beam energy using two different threshold detectors; mica and lexan. The elastic scattering data have been separated from the binary eve nts and used for the determination of quarter-point angle theta (1/4) (equi valent to grazing angle theta (gr),). The values of maximum angular momentu m l(max) radius of interaction R-int and reaction cross-section sigma (exp) (R)(el.) were then deduced by making use of the value of theta (1/4). The d ata of inelastic events of different multiplicities have been used to deter mine partial reaction cross-sections. The sum of the partial cross-sections , therefore, yielded another independent value of reaction cross-section si gma (exp)(R)(inel.) that in turn was used to derive the alternative values of l(max,) theta (gr) and R-int independently. The average of these quantit ies provided the experimental values of the reaction parameters that are co mparable to the theoretical predictions. (C) 2001 Elsevier Science Ltd. All rights reserved.
