Comprehensive evidences of the SU(3) limit in the spdf interacting boson model, a dynamical symmetry describing octupole vibration in rotatonal nucleus , are found in the spectrum, E2 and E1 transition rates, and relative intensities in 158 Gd. This gives a good example of rotational nucleus with octupole vibration in rare-earth region.

The cross section for the production of ω mesons in proton-proton collisions has been measured in a previously unexplored region of incident energies. Cross sections of σ = (7.5± 1.9)μb and σ = (30.8± 3.4) μb (with 20% systematic uncertainties) were extracted at 92 MeV and 173 MeV excess energy, respectively. The angular distribution of the ω at ǫ = 173 MeV is strongly anisotropic, demonstratin...

An array of 3 He-filled proportional counters will be used in the Sudbury Neutrino Observatory to measure the neutral-current interaction of neutrinos and deuterium. We describe the backgrounds to this detection method.
