Surrogate Ratio Method in the Actinide Region Using the (α,α'f) Reaction
نویسندگان
چکیده
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 relative to a known one. To test the SRM we compare the direct-reaction-induced fission probability ratio of 234 U(α, α f) to 236 U(α, α f) with the ratio of cross sections of 233 U(n, f) to 235 U(n, f). These ratios were found to be in agreement over an equivalent neutron energy range of 0.4–18 MeV.

Solvent dependent mechanistic pathways for η-O2CCH3 substitution from the [Mo3(Î1⁄43-O)2(Î1⁄4-O2CCH3)6(η-O2CCH3)3]− anion
Rate coefficients for terminal acetate (g-O2CCH3) substitution from the [Mo3(l3-O)2(l-O2CCH3)6 (g-O2CCH3)3] anion were examined in polar protic (D2O and methanol-d4), polar aprotic (DMSO-d6 and DMF-d7) and acidic solvents (acetic acid-d4). Reaction rates were determined using variable-temperature H NMR and found to span orders of magnitude depending on the solvent (k K (s!1) = 7.2 " 10!6 for D2...
