Description
Fission fragment mass ratio distributions have been measured for the reactions 16O+194Pt and 24Mg+186W, both leading to the same compound nucleus, 210Rn, at near-barrier energies. The measured fission fragment mass ratio variances for 16O+194Pt and 24Mg+186W are compared with the calculations assuming compound nucleus formation. Mass variances of fragments from the 24Mg+186W reaction show a dramatic deviation from the compound nucleus behavior. This suggests strong evidence for onset of the quasifission process in this reaction.
