  13C chemical shifts and 13C–H spin coupling constants (179.7 Hz) of the ylide carbons of two dialkylsulfonium phenacylides show that the ylide carbons are basically sp2. Large upfield shifts (−9.5–−11.8 ppm) of carbonyl carbon signals (δC 181.7 and 179.2) of the ylides from those of the corresponding salts (δC 191.2 and 191.0) suggest significant contribution of a betaine structure.

• Production of krypton and xenon isotopes in thick stony and iron targets isotropically irradiated with 1600 MeV protons

  Abstract— Two spherical targets made of gabbro with a radius of 25 cm and of steel with a radius of 10 cm were irradiated isotropically with 1600 MeV protons at the SATURNE synchrotron at Laboratoire National Saturne (LNS)/CEN Saclay, in order to simulate the production of nuclides in meteorites induced by galactic cosmic‐ray protons in space. These experiments supply depth‐dependent production rate data for a wide range of radioactive and stable isotopes in up to 28 target elements. In this paper, we report results for 78Kr, 80–86Kr isotopes in Rb, Sr, Y and Zr and for 124Xe, 126Xe, 128–132Xe, 134Xe, 136Xe isotopes in Ba and La. Krypton and xenon concentrations have been measured at different depths in the spheres by using conventional mass spectrometry. Based on Monte‐Carlo techniques, theoretical production rates are calculated by folding depth‐dependent spectra of primary and secondary protons and secondary neutrons with the excitation functions of the relevant nuclear reactions. The comparison of the model calculation results with experimental data in the thick target experiments performed at LNS and previously at CERN have allowed adjustments of the poorly known excitation functions of neutron‐induced reactions. Thus, for the two experiments at SATURNE, excellent agreement is obtained between experimental and calculated production rates for most Kr and Xe isotopes in all investigated target elements. Only Xe production in Ba in the gabbro is underestimated by the calculations by ˜25%. This work validates the approach of the thin‐target model calculations of cosmogenic nuclide production rates in the attempt of modeling the interaction of galactic cosmic‐ray protons with stony and iron meteorites in space as well as with lunar samples.

  The 1,6- to 1,2-addition product ratios of the Grignard reactions of benzophenone with t-, s- and n-C4H9MgCl have been compared with the corresponding ratios obtained by the electrolysis of benzophenone in presence of t-, s- and n- C4H9S+(CH3)(2), ClO4- in THF. The Grignard reaction ratios 0.81, 0.50 and 0.19, respectively, were obtained whereas the corresponding electrolysis ratios were 2.26, 1.23 and 1.61. From this comparison of product ratios ii. is concluded that none of the Grignard reactions of benzophenone proceeds through a complete free coupling process of benzophenone radical anions and butyl radicals. The ET character of the Grignard reactions of benzophenone with t-, s- and n- C4H9MgCl was estimated to be 65, 61 and 26%, respectively.
• Evaluating the Probative Value of Child Custody Evaluations

  ABSTRACTIt has previously been argued that a competent forensic work product is defined, in part, by the evaluator's use of conventional forensic methods and procedures applied to child custody evaluations (Gould, 1998) and that the more judges and other legal professionals understand about forensic methods and procedures, the better they are able to critically weigh the substance and merit of a child custody evaluation (Gould & Bell, 2000). These forensic methods and procedures have their foundation in the behavioral sciences and are characteristic of competent and comprehensive forensic evaluations conducted for other legal purposes. In this paper, we provide a more detailed model for critiquing the forensic competence of a child custody report. Such a model better assists courts and lawyers in understanding how to assess the substance and admissibility of custody reports.
