The magnetic field and pressure effects in the photolysis of deuteroformaldehyde and sulfur dioxide in the near ultra-violet reagion have been investigated. A two-level model is proposed to interpret the results obtained. 相似文献

The reaction 6Li (e, e′p)5He has been investigated with a resolution good enough to distinguish the effects of the s- and p-shells of the 6Li nucleus. The reaction cross section has been measured as a function of the missing energy from −15 to +30 MeV. The proton angular distribution has been measured at missing energies of 4 and 20 MeV. The comparison of the data with calculations within the framework of the plane-wave impulse approximation gives the harmonic oscillator parameters qp = 50 ± 5 MeV/c,qs = 108 ± 9 MeV/c. 相似文献

We obtain the solution to the equations of motion for a classical particle with spin, electric and magnetic charges, and electric and magnetic normal and anomalous moments, in the field of a plane electromagnetic wave. An explicit form of the solution is given for linearly polarized waves and monochromatic circularly polarized waves. The possibility is noted that due to the presence of the moments, the particle can be accelerated to speeds arbitrarily close to the speed of light.Translated from Izvestiya Vysshykh Uchebnykh Zavedenii, Fizika, No. 11, pp. 71–74, November, 1981. 相似文献

Switchover from a runaway-electromnduced volume discharge to a spark is studied when a nanosecond discharge is initiated in
high-pressure nitrogen an d air at a voltage of 50–250 kV. In the case of a cathode with a small radius of curvature and a
flat anode and in the presence of cathode spots, the leader of the spark channel may propagate from the flat cathode. When
the rate of rise of the voltage across centimeterwide gaps is high (dU/dt ∼ 1015 V/s or higher), cathode spots in the case of a corona discharge emerge within 200 ps. 相似文献

We use the time-differential perturbed angular correlation technique to study nuclear electric quadupole hyperfine interactions
of probe 111Cd nuclei in cerium lattice sites at room temperature under pressures up to 8 GPa. We have found that the well known γ → α
phase transition in cerium is not isostructural. In α-Ce, the probe 111Cd nuclei reveal a quadrupole electron charge density component that is absent in γ-Ce. The hidden spacial structure of electronic
quadrupoles in α-Ce is triple-q antiferroquadrupolar, as was suggested in [14]. We relate our findings to the current understanding
of the γ → α phase transition and also report on nuclear quadrupole interactions in other high-pressure phases of cerium:
α″ (C2/m space symmetry) and α′ (α-U structure). 相似文献

Sub-Doppler laser cooling in a magneto-optical trap for thulium atoms at a wavelength of 410.6 nm has been experimentally
studied. Without any dedicated molasses period of sub-Doppler cooling, the cloud of 3 × 106 atoms at a temperature of 25(5) μK was observed. The measured temperature is significantly lower than the Doppler limit of
240 μK for the cooling transition at 410.6 nm. The high efficiency of the sub-Doppler cooling process is due to a near-degeneracy
of the Landé g-factors of the lower 4f
