The 13C enrichment observed in the first order photolytic decomposition of dibenzylketone (1,3-diphenyl2-propanone) was studied as a function of solvent viscosity and temperature. The isotope effect is due to electron-nuclear hyperfine interactions in the free radical intermediates of the reaction. The results are explained using a continuum diffusion model and a simplified version of the radic...

The 9Be(32Ar, 31Ar)X reaction, leading to the 5/2+ ground state of a nucleus at the proton drip line, has a cross section of 10.4(13) mb at a beam energy of 65.1 MeV/nucleon. This translates into a spectroscopic factor that is only 24(3)% of that predicted by the many-body shell-model theory. We introduce refinements to the eikonal reaction theory used to extract the spectroscopic factor to cla...

electrode potential of 2-(2,3-dihydroxy phenyl)-1,3-dithiane (dpd) was investigated by means of cyclic voltammetry (cv) at various potential scan rates. the calculated value was compared with the experimental value obtained by cyclic voltammetry (cv). all experiments were done in aqueous phosphate buffer solutions at different phs. the experimental redox potential of dpd was obtained to be 0.75...

The emergence of nuclear weapons as a new actor in international relations has introduced a new area in the international security arena. Since the appearance of these weapons, there have been increasing efforts to limit and destroy them in order to achieve global peace in the framework of disarmament and centered around the Treaty on the Non-Proliferation of Nuclear Weapons. Along with the eme...
