Angular momentum dependence of complex fragment emission.
The angular momentum dependence of large fragment production in long lived reactions is studied by measurements of fragment cross sections from reactions with substantially different angular momentum distributions and the coincident y-ray multiplicity distributions. The results indicate that the primary l-wave distributions move to larger mean values and decrease in width and skewness with incr...
متن کاملEmission of unstable clusters from hot Yb compound nuclei
Neutrons and isotopically resolved light charged particles have been detected in coincidence with evaporation residues produced in the reaction E/A511 MeV Ni1Mo. Multiplicities of evaporated particleunstable clusters have been determined from correlations in the emission of these light particles. The decay of the short-lived He and Be (E*53.04 MeV) states was found to be affected by the Coulomb...
متن کاملMass-asymmetric barriers from excitation functions for complex-fragment emission.
The conditional saddle-point heights (conditional barriers) that preside over the emission of complex fragments (Z = 2—11) from compound nuclei have been obtained from the excitation functions of individual fragments in the reaction He+""Ag. The magnitudes of the barriers and their dependence on mass asymmetry may be used to verify important features of the potential-energy surface including sh...
متن کاملPresupposition Role in the Compound-Complex Sentence
The article analyzes the role of presupposition in the compound-complex sentence. The authors examine the types of presuppositions and minimal compound-complex sentence as a field of presuppositions action. The analysis of these types of sentences by the material of the English language shows that several kinds of presuppositions are realized in them – contact or distant, - developing in the re...
متن کاملCharged - particle evaporation from hot 164 Yb compound nuclei and the role of 5 He emission
A systematic study of the decay properties of Yb compound nuclei with excitation energies of 100–300 MeV was performed. The emission patterns of light charged particles detected in coincidence with evaporation residues produced in Ni1 Mo and O1 Sm reactions have been measured and compared to statistical model predictions. There is found to be significant disagreement between the experiment and ...
