A magnetic isotope effect was found in the photochemical reduction of uranyl nitrate by p-methoxyphenol. The initial238U/235U ratio equal to 8.93±0.008 was altered during the reaction to 8.945±0.008-8.970±0.005 in the reaction product, namely, uranium tetrafluoride.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, pp. 1902–1903, August, 1990. 相似文献

The matrix hodoscope of the OKA experimental setup and a prototype of the hodoscope for the NA62 experiment are described.
The design of both hodoscopes is presented. The requirements for the hodoscope prototype are listed, and the efficiency and
the time resolution obtained on the basis of experimental data are quoted. 相似文献

This paper reports on the results of investigations into the temperature and spectral dependences of the magnetic circular dichroism in Dy1?xNix-Ni bilayer films prepared through thermal sputter deposition of components under ultrahigh vacuum. The distribution of the components over the layer thickness is examined by Auger spectroscopy. The nickel content x in Dy1?xNix layers varies from 0.005 to 0.06. It is shown that, in the temperature range 80–300 K, the contribution made to the magnetic circular dichroism by a Dy1?xNix layer in a bilayer film with a nickel content higher than the threshold value is approximately equal to the magnetic circular dichroism observed in an isolated Dy1?xNix film at temperatures below the temperature of the phase transition to a ferromagnetic state (~100 K). This phenomenon is explained by magnetic ordering in the Dy1?xNix layer of the bilayer film due to the combined effect of two factors, namely, the incorporation of nickel into a dysprosium layer and the presence of a continuous nickel sublayer in the film. 相似文献

The relaxation of the Q1(—*) excited state of the nonprotonated Fc4PH2 and diprotonated Fc4PH4
2+ forms of meso-tetraferrocenylporphyrin was studied by femtosecond laser absorption spectroscopy. Transition from the Q1(—*) state to the charge-transfer state was shown to occur within 208±10 fs for Fc4PH2 and 9±3 ps for Fc4PH4
2+. A fast vibrational relaxation with a characteristic time of 120—140 fs was found for both forms. The relaxation time of Fc+—P– charge-transfer state for Fc4PH2 was 17±4 ps. 相似文献
