摘要: Abstract Hot nuclei produced in the reactions of 261 MeV and 490 14 N with 154 Sm have been studied. The initial properties these nuclei; excitation energies, angular momenta temperatures, characterized through measurements residue velocities, gamma ray multiplicities α-particle energy spectra. Nuclei energies as high 400 temperatures 6 are produced. Determinations variation temperature for A ⋍ 160 indicate that apparent level density parameter a , defined E ∗ |T 2 changes from /8 at low to ≈ /13 energy. Effective particle emission barriers suggest large shape fluctuations during de-excitation cascade. At 35 MeV/u momentum transfer linear incomplete fusion is reasonable agreement values calculated using geometric overlap model.
