The reaction π? p→η′η′n has been studied atp π=37 GeV/c. Total of 14 events of this reaction have been selected. It has been shown that in the effective mass spectrum of the η′η′ system the events are concentrated mainly near the reaction threshold, which might be caused by the decayX(1910)→η′η′. The reaction cross-section has been evaluated: σ(π? p→η′η′n)=110±40 nb.  相似文献

The decayf 1(1285)→ρ0(770)γ was studied at VES spectrometer of IHEP. Clear signal off 1(1285) is seen in the effective mass spectrum of the π+π?γ system in the reaction π?γN→π+π?π?γN at the momentum $P_{\pi ^ - } = 37 GeV/c$ . The branching fraction of decayf 1(1285)→ρ0(770)γ has been found to be $$BR(f_1 (1285) \to \rho ^0 (770)\gamma ) = (2.8 \pm 0.7(stat) \pm 0.6(syst)) \cdot 10^{ - 2} .$$ The ratio of the helicity amplitudes for ρ0 meson in its rest frame was determined by the analysis of angular distributions: $$\rho _{00} /\rho _{11} = 3.9 \pm 0.9(stat) \pm 1.0(syst).$$   相似文献

The mechanism of depolymerization of polymeric p-dinitrosobenzene in vulcanization of unsaturated rubbers is analyzed. The results obtained explain why the vulcanizing activity of p-dinitrosobenzene decreases in the course of its prolonged storage.__________Translated from Zhurnal Prikladnoi Khimii, Vol. 78, No. 2, 2005, pp. 320–323.Original Russian Text Copyright © 2005 by Klyuchnikov, Chachkov, Deberdeev, Zaikov.  相似文献
