[en] Aqueous toluene solutions have been irradiated with Co γ-rays. In unbuffered solutions the various cresol isomers are formed in a total yield of 0.45, 0.87 and 0.94 molecules/100 eV absorbed energy in argon-, N₂O- and air - saturated solutions, respectively. The yields are reduced in acid (pH 3) solutions (G 0.14, 0.14 and 0.52, respectively) but the reduction is compensated by the formation of 1,2-di-phenylethane in yields of 0.49 and 1.60 in argon- and N₂O-saturated solutions, respectively. Benzyl radicals are formed through an acid catalysed water elimination reaction from the initially formed hydroxymethylcyclohexadienyl radical. Phenyltolylmethanes, dimethylbiphenyls and partly reduced dimers are also formed during the radiolysis. Hydrogen is formed in the same yield as the molecular yield, g(H₂). Xylene isomers and benzene are formed in trace quantities. The most remarkable effects of the addition of Fe(III) ions to deaerated acid toluene solutions are the formation of benzyl alcohol and benzaldehyde and an increase in the yield of 1,2-diphenylethane

[en] This book presents the papers given at a conference on high energy physics. Topics considered at the conference included synchrotron radiation, testing the standard model, beyond the standard model, exploring the limits of accelerator technology, novel detector ideas, lepton-lepton colliders, lepton-hadron colliders, hadron-hadron colliders, fixed-target accelerators, non-accelerator physics, and sociology

[en] The authors summarize the results of the standard model group which has studied the ways in which different facilities may be used to test in detail what is now called the standard model, that is SU/sub c/ x SU x U

[en] The mass spectrum of dimuons produced by 400 GeV/c protons in tungsten was measured for masses greater than 7 GeV. A clear resonant signal of 2700 upsilons was seen. The dependence of dimuon production on x/sub F/ and p/sub T/ was determined for dimuon masses in the range 7.0 to 8.25 GeV as well as for masses in the upsilon region 8.25 to 9.75 GeV

[en] Tasks reported on include: exploration of issues of demand for test beams, and particularly for high energy; fleshing out the possibilities of the High Energy Booster beams; and seeking inexpensive ways of providing high energy facilities

[en] Permanent magnets built using strontium ferrite bricks have been tested for stability against demagnetization. Ten test dipoles were built to monitor ferrite behavior under a variety of stressing conditions, including irradiation, mechanical shock, extreme thermal excursions, and long term magnetization stability. The test magnets were geometrically similar to, but much shorter than, the magnets built for the 8 GeV transfer line at FNAL. No loss of magnetization was observed for bricks exposed to a proton beam, and a magnet exposed to several Gigarads of Co⁶⁰ gamma radiation suffered no measurable demagnetization. The magnet strength was observed to decrease logarithmically with time, consistent with the expected effect of thermal fluctuations. Irreversible demagnetization of ∼0.1% was seen in cooling magnets to 0 degree C, and the loss was ∼0.2% for magnets cooled to -20 degree C. No additional demagnetization was seen on subsequent cycling to 0 degree C. Finally, one of the long dipoles built for the 8 GeV line was periodically tested over the course of 3 months, and showed no measurable demagnetization

[en] The benefits of an electron--proton colliding beam facility at Fermilab are reviewed. Examples of experiments that can be done are: weak interactions, e + p → νe + hadrons; deep inelastic scattering, e + p → e' + hadrons; hadron jets; and photo-production. The addition of the electron--proton colliding beam capability is recommended

[en] We describe the energy, position, and angular resolutions of an electromagnetic calorimeter consisting of 56 layers of proportional wire and lead-filled tubes. The calorimeter was tested with two different electronic readout systems in a beam of electrons with energies ranging from 10 to 200 GeV. (orig.)

[en] We describe the experimental apparatus used by the APEX experiment (Experiment 868) at the Fermilab antiproton accumulator. The experiment is designed to search for decays of 8.9 GeV/c antiprotons as they traverse a 3.7 m long evacuated decay tank inserted in a straight section of the antiproton accumulator ring. The detector components in the experimental set-up are discussed individually, and the performance of the experiment during data-taking is described. (orig.)

[en] We report on the search for anti-proton decay at the Fermilab Antiproton Accumulator Ring. Experiment 868 (APEX) was designed to search for two-body p-bar decay modes containing an electron in the final state (p-bar→e+X) and to conduct an exploratory search for decays with a muon in the final state (p-bar→μ+X). Data were taken for three months in the Spring of 1995. Preliminary results yield lower limits on τ_p-bar/BR in the range of 10⁵-10⁶ years for selected channels having an electron in the final state, improving on previous results by approximately 3 orders of magnitude. Additionally, we report the first preliminary results for the p-bar→μγ and p-bar→μπ⁰ decay channels
