Isospin Splitting

The 90° differential cross section of the 9Be(d, γ0)11B reaction has been measured at deuteron energies from 3 to 12 MeV. The results of this experiment are consistent with a recent calculation of the dipole states of mass 11 nuclei, and with measurements of the 11B(γ, nγ′) and 11B(γ, pγ′) processes, and confirm the isospin splitting of the giant resonance in 11B.

Theoretical Results

The Lorentz-invariant differential cross section (LIDCS) for π production in heavy ion collisions was studied through the two-step process, NN→NΔ→NNπ. A phenomenological interaction potential containing central and tensor terms was used. The effect of inclusion of the tensor term on the LIDCS was little. The target nucleus 12C was excited to one of its giant resonance states, Jπ=1+, T=1, while the projectile nucleus 16O was excited to an isobar Δ (M=1232 MeV , ΓΔ=115.11 MeV ) which decayed (NΔ→NNπ), giving a nucleon and a pion mπ=138 MeV . In comparison with available experimental data, the shape was reproduced, but the theoretical results were higher.

Sensitive Testing

It is pointed out that the y-dependence of the differential cross-section for various types of neutrinos on the electron promises to be a sensitive testing ground of the electroweak Standard Model at KAON in Vancouver. Estimates of the flux requirements are given and the feasibility of such experiments is discussed.
