[en] Just as bar ³He can be approximately characterized as a polarized neutron target, polarized ⁶LiD has been advocated as a good isoscalar nuclear target for the extraction of the polarized gluon content of the nucleon. The original argument rests upon a presumed open-quotes alpha+deuteronclose quotes picture of ⁶Li. The authors have calculated the polarization of the constituents of ⁶Li as a three-body bound state of α+n+p interacting with local potentials fitted to the scattering data. It is necessary to include partial waves up to j = 13/2 (57 channels) in the Faddeev equations before the energy eigenvalue converges. The longitudinal formfactors are then described well by the wave function. Various combinations of αN and NN strong and Coulomb potentials yield a straight line in the charge radius vs. energy plane which passes through the experimental datum. The authors find for all cases a polarization of the neutron in excess of 90%, which may make ⁶Li an attractive target for many nuclear physics purposes as well

[en] The environmental characterization program for the Fusion Materials Irradiaton Test (FMIT) facility is presented. Requirements for the development and testing of Magnetic Fusion Energy (MFE) materials together with the complexity of the FMIT (d,Li) generated radiation field warrant a multifaceted dosimetric approach. Specific passive, active and calculational dosimetry efforts comprising this multifaceted approach are described. Special emphasis is given to those dosimetry capabilities uniquely required to characterize FMIT

[en] The interest of the π-nucleus interaction at low energy is discussed. The threshold photoproduction has become an operationnal tool for concrete investigations in this area. The experiments already completed are described in details, and the interpretation of their results is critically examined. The possible future in this field is sketched

[en] Transmission measurements have been made at ORELA upon two metal samples of ⁶Li(98.72 percent) with inverse sample thicknesses of ⁶Li of 11.99 and 2.987 b/atom. The measurements at low energies (from 10 eV to 300 keV) were made using a ⁶Li glass scintillation detector at 17.878 m and 78.203 m and at high energies (from 50 keV to approximately 10 MeV) using an NE-110 scintillation detector at 78.203 m. The total cross section data from both samples and detectors are in good agreement and are believed to be accurate to 1 to 2 percent below 1 MeV. Total cross section data obtained from both samples at approximately 25 discrete energies up to 1 MeV using an iron-filtered beam are in good agreement with the continuous spectra data. 1 table, 2 figures

[en] Measurements of the nuclear reaction ⁶Li(p,γ) ⁷Be have been carried out at the 5.5 MV Van de Graaff Tandem accelerator of NCSR 'Demokritos'. The detection system consists of ¹⁰NaI(Tl) detectors operating as a summing crystal, covering nearly 4π geometry with absolute efficiency (≅54%). (author)

[en] Differential and total cross sections for π⁺ absorption on ⁶Li leading to the pp +⁴ He_g.s, pp +⁴He and pp + X final states are presented. The energy dependences of these reactions are different and are found to depend on the underlying reaction mechanism and nuclear structure. We conclude that the contributions of non-quasi-deuteron absorption mechanisms are small

[en] Results of water tests of the lithium target design for the Fusion Materials Irradiation Test (FMIT) Facility demonstrate hydraulic features essential for acceptable target operation and confirm predictions of the target performance. This high speed, free surface, curved-wall jet has been shown to generate a stable surface shape and to provide the high velocities and pressures within the fluid needed to remove the 3.5 MW of power generated within the jet during FMIT operation. Measurements of the jet performance are found to fall within limits bounded by one- and two-dimensional potential flow predictions. This agreement between measured and predicted performance provides for a significant level of confidence in the ability of the FMIT lithium target to meet its design and functional objectives

[en] Development of the liquid lithium target for the Fusion Materials Irradiation Test (FMIT) Facility is described. The target concept, major design goals and design requirements are presented. Progress made in the research and development areas leading to detailed design of the target is discussed. This progress, including experimental and analytic results, demonstrates that the FMIT target design is capable of meeting its major design goals and requirements

[en] The ratio of positive pion photoproduction cross-sections on ⁶Li and protons was measured near the threshold. The result is considerably lower than the existing theoretical predictions

[en] With Tz = 0, the E 1 transition of ΔT = 0 is prohibited in ⁶Li nuclei. By experiment, the d spectrum in ⁶Li (e, e'd) ⁴He was already measured. To see whether the nuclear reaction is due to iso-spin impurity of ⁶Li or to other absorption than E 1, the angular distribution has been measured. The target is a 98.7% enriched ⁶Li plate of 20 mg/cm² thickness. At electron energy of 14, 20 and 30 MeV, and angle between 42⁰--138⁰, the measurement was carried out. (Mori, K.)
