| Popis: |
The [ital U]-like [ital K]-vacancy production probability in 7.5-MeV/nucleon deep-inelastic [sup 238]U+[sup 238]U collisions has been measured for no-fission, single-fission, and double-fission exit channels. The results are interpreted using quasimolecular orbital correlations for diatomic and triatomic configurations. This leads to the determination of lower limits for the time scale for late fission of U-like products ([ge]8 and [ge]4 as) and their probability ([ge]77% and [ge]52%), at mean initial-excitation energies of [similar to]40 and [similar to]105 MeV, respectively. |
