Utilizing (p,d) and (p,t) Reactions to Obtain (n,f) Cross Sections in Uranium Nuclei Via the Surrogate-Ratio Method

Utilizing (p,d) and (p,t) reactions to obtain (n, f) cross sections in uranium nuclei via the surrogate-ratio method The surrogate ratio method has been tested for (p, d) and (p, t) reactions on uranium nuclei. 236 U and 238 U targets were bombarded with 28-MeV protons and the light ion recoils and fission fragments were detected using the Silicon Telescope Array for Reaction Studies detector a...

Surrogate Ratio Method in the Actinide Region Using the (α,α'f) Reaction

In the Surrogate Method, the measured decay probability of a compound nucleus formed via a direct reaction is used to extract the cross section for a reaction with a different entrance channel that proceeds through the same compound nucleus. An extension of the Surrogate Method, the Surrogate Ratio Method (SRM), uses a ratio of measured decay probabilities to infer an unknown cross section rela...

Surrogate Measurement of the 238Pu(n,f) Cross Section

The neutron-induced fission cross section of 238 Pu was determined using the surrogate ratio method. The (n,f) cross section over an equivalent neutron energy range 5–20 MeV was deduced from inelastic α-induced fission reactions on 239 Pu, with 235 U(α, α f) and 236 U(α, α f) used as references. These reference reactions reflect 234 U(n,f) and 235 U(n,f) yields, respectively. The deduced 238 Pu...

Total domination in cubic Knodel graphs

A subset D of vertices of a graph G is a dominating set if for each u ∈ V (G) \ D, u is adjacent to somevertex v ∈ D. The domination number, γ(G) ofG, is the minimum cardinality of a dominating set of G. A setD ⊆ V (G) is a total dominating set if for eachu ∈ V (G), u is adjacent to some vertex v ∈ D. Thetotal domination number, γt (G) of G, is theminimum cardinality of a total dominating set o...
