[en] The nuclear physics group used the on-line isotope separator to make direct mass doublet measurments for the first time and to identify a new α-emitter, hafnium-162. A new NaI(Tl) detector gave improved data on the multiplicities and intensities of continuum γ-rays in gadolinium-147. Beam profile data for the Fast Intense Neutron source showed that tritium loss from bombarded targets is not caused by beam hot-spots. Geometry studies on the High Current Proton Accelerator showed that proton fraction increases with improved arc and gas efficiencies. In conjunction with fertile-to-fissile conversion experiments at TRIUMF, two types of monitoring foils agreed within 2.5% with results obtained by two other laboratories. Neutron diffraction data for a single β-N₂ crystal at 0.4 MPa showed that its scattering density distribution and mean translation displacements have almost perfect spherical symmetry. A new non-linear stress analysis code was marketed
