Two-Step Contribution to Intermediate Energy (p, p') and (p, n) Reactions

Two-Step Contribution to Intermediate Energy (p,p′) and (p,n) Reactions

We calculate the two-step contribution to (p, p′) and (p, n) reactions at intermediate energy. We describe the motion of the incident nucleon with a plane wave and compare the contribution from two-step processes with that from one-step processes. To describe the two-step processes, we extend the response functions to nondiagonal forms with respect to the momentum transfer q. We performed a num...

REACTIVITY OF N-SUBSTITUTED p-BENZO AND p-NAPHTHOQUINONEIMINE N-OXIDES TOWARD DIPOLAROPHILES

The dipolar cycloaddition reactivity of N-(1-naphthy1)-1,4- benzoquinoneimine N-oxide and N-phenyl-1,4- naphthoquinoneimine Noxide are investigated, The latter gives the expected adducts with common dipolarophiles such as acrylonitryle, methyl methacrylate, dimethylacetylene dicarboxylate and N-phenylmaleimide. The reactivity of the former nitrone is found to be minimal. It undergoes, how...

On the reactions p + p → p + Λ + K + and p + p → p + Σ 0 + K + near thresholds

The cross sections for the reactions of the strange production p + p → p + Λ + K+ and p + p → p + Σ0 + K+ near thresholds of the final states pΛK+ and pΣ0K+ are calculated in the effective Lagrangian approach. Our approach is based on the dominant contribution of the one–pion exchange and strong interaction of the colliding protons in the initial state. The theoretical values of the cross secti...

N,P,P-Triisopropyl­phosphinic amide

The title compound, C(9)H(22)NOP, was obtained by slow diffusion of oxygen into a toluene solution of (i)Pr(2)PNH(i)Pr. In the crystal, an inter-molecular N-H⋯O hydrogen bond occurs.
