Description

We have measured at SARA the correlation of fission fragments produced in the reactions 20Ne + 197Au and 20Ne + 209Bi at 30 MeV/u. The results show that the most probable amount of linear momentum transferred from the projectile to the fissioning nucleus is about 80%. This corresponds to about 3.7 GeV/c. The fission cross section is still rather large at this bombarding energy: 1.6 +- 0.3 b for the Au target and 2.2 +- 0.5 b for the Bi one. We present the results of a Monte-Carlo simulation which allows us to reproduce most of the experimental data under certain conditions which are discussed. (orig.)
