TL;DR: In this article, measurements of ψ(3097) and ψ′(3686) branching fractions for selected hadronic decays are presented, and it is shown that the ratio of branching fractions to lepton pairs for the decays to pπ and K*K for which this ratio is substantially smaller.
Abstract: Measurements of ψ(3097) and ψ′(3686) branching fractions for selected hadronic decays are presented The ratio of ψ′ to ψ branching fractions for these decays is consistent with the ratio of branching fractions to lepton pairs, with the exception of the decays to pπ and K*K for which this ratio is substantially smaller © 1983 The American Physical Society

TL;DR: In this article, the authors studied the two-photon interactions with the SLAC-LBL Mark II magnetic detector at SPEAR and determined upper limits on the radiative width of the f(1270), A{sub 2}(1310) and f'(1515) tensor mesons.
Abstract: Two-photon interactions have been studied with the SLAC-LBL Mark II magnetic detector at SPEAR. The cross section for {eta}' production by the reaction e{sup +}e{sup -} {yields} e{sup +}e{sup -}{eta}' has been measured at beam energies from 2.0 GeV to 3.7 GeV. The radiative width {Lambda}{sub {gamma}{gamma}}({eta}') has been determined to be 5.8 {+-} 1.1 keV ({+-}20% systematic uncertainty). Upper limits on the radiative widths of the f(1270), A{sub 2}(1310) and f'(1515) tensor mesons have been determined. A search has been made for production of the E(1420) by {gamma}{gamma} collisions, but no signal is observed.

TL;DR: The conformations of the adducts derived from the covalent binding of the two enantiomeric forms of 9,10-epoxy-9,10,11,12-tetrahydrobenzo(e)pyrene (BePE) with native DNA were investigated by the electric linear dichroism technique.
Abstract: The conformations of the adducts derived from the covalent binding of the two enantiomeric forms of 9,10-epoxy-9,10,11,12-tetrahydrobenzo(e)pyrene (BePE) with native DNA were investigated by the electric linear dichroism technique. Both enantiomers give rise to two major adducts, one of which appears to be a quasi-intercalative site (I) while the other one is an external binding site (II). While the overall linear dichroism spectra are similar, in the case of the (—) enantiomer there is a greater contribution of site II adducts. These results are markedly different from the ones obtained with the two enantiomers of anti-benzo(a)pyrene-7,8-diol-9,10-epoxide (BaPDE), where the (+) enantiomer gives rise almost exclusively to site II binding, while the (—) enantiomer gives rise to both site I and site II covalent binding. The differences in the heterogeneity of binding between BePE and anti-BaPDE enantiomers may be due to the absence of hydroxyl groups in BePE which, in the case of BaPDE, are an impo...
