| Résumé : |
Projectile-like fragments from reactions of 15 MeV/nucleon ⁵⁶Fe with targets of ⁵⁶Fe and ²³⁸U have been measured as a function of total kinetic energy loss.
The mass and charge distributions for each fragment were determined with discrete resolution. The main detector system for the energy measurement was a large ionization chamber with 80 cm active thickness. The timing system consisted of two channel-plate fast timing devices (CPFTD) which were used as start and stop detectors. A timing resolution of 250 psec, a mass resolution of 0.8 mass units and a charge resolution of 0.4 charge units were obtained with this system. Data were analyzed as a function of energy loss by fitting a two dimensional Gaussian function to the neutron-proton distributions. Results are given for the measured data as well as estimates of the primary fragment distributions after correction for neutron evaporation. A comparison with low energy data (8.3 MeV/nucleon) is made. |
