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